Preface to the Current Edition Human Anatomy and Physiology (A&P) is a two-semester course sequence (BIO 23 & BIO 24) offered by the Biological Sciences Department at Bronx Community College (Meister Hall 418).

BIO 23 and BIO 24 are conducted in an integrated lecture-laboratory format for the study of physiological processes, as well as gross and microscopic anatomy. The six hours of class contact hours per week is equally divided between the lecture and laboratory meetings within a 14-week academic semester followed by a final lecture examination in the 15th week of the academic semester.

BIO 23 covers the following topics and systems of the human organism: human structural and functional organization, basic chemistry, cell structure and function, foundations of cell metabolism, histology, the integumentary system, the skeletal system, the muscular system, the nervous system, and the endocrine system.

BIO 24 applies essential concepts from BIO 23 in the study of the following topics and systems of the human organism: cardiovascular system, lymphatic system and immunity, respiratory system, urinary system and fluid and electrolyte balance, digestive system and metabolism, and the reproductive system.

The coordinators of the course are Prof. Abass Abdullahi, Prof. Kyeng Lee, and Prof. Carlos Liachovitzky.

This guide is the product of the collaborative effort of many faculty of the Department of Biological Sciences. It has been mutating since the first edition up to the present. This guide is a continuous work in progress thanks to the input of students and faculty of the department. Dr. Howard Fuld and Dr. Henry Hermo authored the first version in Fall 1988, and many others contributed along its history. Thanks to Dr. Maureen Gannon, who reviewed extensively the first editions; and to Dr. Nichole McDaniel, Dr. Shylaja Akkaraju, and Prof. Carlos Liachovitzky, who contributed widely with the most recent versions.

*Your instructor may modify the standard grading. If so, s/he will announce it the first day of classes **Practical means that you will be answering questions based on real specimens and models; your instructor will describe the format in more detail Dropped Exams and Quizzes Lecture: If any one of your in-class exam scores is lower than your final exam score, then the score for the in-class exam will be dropped and the final exam will be counted twice. If your final exam score is lower than all of your other exam scores, then nothing will be dropped and the final will be worth the same as your other exams. Under no circumstances will more than one exam grade be dropped.

Lab: The instructor may drop the two lowest quiz grades. Under no circumstances will the midterm or final practical exam grades be dropped Make-ups Make-up exams WILL NOT be given under any circumstances. However, if you know in advance that you must miss an exam, the instructor may allow you to take the exam early.

Extra Credit Extra credit is generally discouraged, but under no circumstances is extra credit to exceed 3% of the grade. Absolutely no extra credit assignments will be given to individual students.

Note: Your lecture and/or lab instructor may make changes to the number and content of assignments and exams, thus the percent distribution of grades may be different from those described above. If so, he or she will describe the grading policy to the class at the beginning of the semester.

Attendance Bronx Community College currently requires your instructor to take and file attendance records for every class. It is your responsibility to arrive at class on time and to be aware of the calendar of class meetings for your section.

The Department defines an excessive absence record as unexcused absences of more than 20% of scheduled class time. Students with an excessive absence record will receive an automatic grade of F in the course at your instructor’s discretion. Total scheduled class time includes lab, lecture, and online attendance, as required by the particular course.

Instructors also have the right to mark students absent if they arrive late or leave early from class.

Instructors are not required to grade tests and other forms of assessment of students with an excessive absence record. Instructors are also not required to offer makeup exams for students absent from scheduled exams.

Registration and prerequisites It is expected that students will meet minimum prerequisites (BIO 23) as described in the schedule of classes distributed by the Office of the Registrar. At least a C+ grade in BIO23 is recommended.

Switching sections Students are not allowed to switch sections. This is not a decision up to your instructor, but a Biology Department policy.

Overtallying The Biology department does not overtally. This is not a decision up to your instructor, but a Biology Department policy. A section is closed once it reaches the maximum numbers of students allowed.

Credit hours and workload This course is worth four credits. It meets 6 hours per week (3 hours of lecture and 3 hours of laboratory).

You should be aware of the challenge that this course will place upon your time and effort and should choose a semester schedule of classes that allows for the demands of the course. If your previous educational background does not include coursework in the sciences (more specifically in the biological sciences), you should arrange your schedule so that you have at least 12 hours a week to devote to this course.

Children College regulations and common courtesy for your classmates prohibit the presence of children in either lecture or laboratory classrooms. Furthermore, children may NOT be left unattended in the common areas outside of classrooms for their own safety. Even if you already have childcare arrangements, you might consider using the referral service offered by the BCC Early Childhood Center (ECC). They will refer you to licensed daycare providers that you can use full time or in an emergency if your regular childcare services fall through. If your child is between 2 years, 9 months and 4 years old, you may enroll him/her in the ECC preschool. Fees are adjusted according to income, but there is usually a waiting list. Lastly, for evening students with school-age children, there is an after-school program in which you can enroll your child (also for a fee). Whatever your choice, please make arrangements (and back-up arrangements) for appropriate childcare prior to class attendance. See info about the Early Childhood Center here: https://www.bcc.cuny.edu/Early-Childhood-Center/

Cell Phones and Other Electronic Devices Common courtesy and appropriate classroom behavior dictate that the use of cell phones (incoming and outgoing) is both rude and inappropriate at any time during class. Your cell phones should be off or on silent mode when you enter the classroom. During exams, these devices MUST be turned off. No exceptions.

Access and Equal Education Opportunity for Students The mission of Disability Services is to provide access and equal educational opportunity for students with disabilities, enabling them to succeed academically, socially, and professionally. See more here: http://www.bcc.cuny.edu/Disability-Services/, or contact the Disability Services Office (Loew Hall, Room 211, 718.289.5874).

University Policies on Academic Dishonesty (a.k.a. cheating) Academic dishonesty is prohibited at The City University of New York and is punishable by penalties, including failing grades, suspension, and expulsion, as provided here.

The following are some examples of cheating, but by no means is it an exhaustive list: ✓ Copying from another student during an examination or allowing another to copy your work.

Unauthorized collaboration on a take-home assignment or examination ✓ Using notes during a closed book examination ✓ Taking an examination for another student or asking or allowing another student to take an examination for you ✓ Changing a graded exam and returning it for more credit ✓ Submitting substantial portions of the same paper to more than one course without consulting with each instructor 15

✓ Preparing answers or writing notes in a blue book (exam booklet) before an examination ✓ Allowing others to research and write assigned papers or do assigned projects, including use of commercial term paper services ✓ Giving assistance to acts of academic misconduct/dishonesty ✓ Fabricating data (all or in part) ✓ Submitting someone else's work as your own ✓ Unauthorized use during an examination of any electronic devices such as cell phones, palm pilots, computers or other technologies to retrieve or send information.

Instructor and Student Responsibilities Anatomy and physiology are fascinating subjects, but also quite challenging. This outline of instructor and student responsibilities is intended to help you navigate the course and all of its requirements to maximize your success and minimize your frustration. hour(s) during which he or she is expected to be in his or her office to address student concerns. If these times do not work for you, you may request that your professor schedule an appointment with you at another time.

Instructor responsibilities It is the instructor’s responsibility to: 1. Start and end class on time. The instructor should not hold the class significantly beyond the end of class, nor should he or she dismiss class excessively early.

2. Conduct class in a manner that is unbiased and respectful.

3. Present relevant material. The instructor should present the material that is most important for you to learn and understand in your study of A&P. The method (PowerPoint, chalkboard) and style (lecture, skits, worksheets, etc) that your instructor uses is entirely up to him or her.

4. Notify you of changes to the syllabus. The instructor may decide to change the number, timing or coverage of exams, or to otherwise adjust the syllabus. In such cases, the instructor must notify students by making an announcement in class of the change(s). The instructor is not responsible for students who do not hear the announcement because they were either not present or not paying attention.

5. Give and grade exams in a timely fashion.

The instructor should notify students when they can expect to receive graded exams.

However, the time required to grade exams will vary according to the nature of the exam (scantron, short answer, essay, etc.).

6. Be available during scheduled office hours.

The instructor will have scheduled office

Your instructor is NOT required to: i. give handouts or provide lecture notes ii. return exams or quizzes for you to keep iii. give review sessions or review sheets Student Responsibilities We hear over and over again “I failed because I had a bad instructor.” While few would argue that a great instructor makes being in the class more exciting, no instructor is responsible for your failure or your success; both depend on the amount and quality of work you put into the course.

Ultimately, your performance in this and any class is your responsibility—it is squarely on your own shoulders. To that end, it is your responsibility to: 1. Prepare. Read the material for lecture and for laboratory at least once before you come to class. Use lab and lecture handouts to focus your reading on the most important topics. Observe the various diagrams, figures and tables and correlate each to the text. Take notes while you read. Write any questions that you think of in the margins or in your notebook.

2. Be present. Attend every class session and be there on time. Many instructors begin 16

class by taking attendance. If you are late for this, it is your responsibility to notify the instructor after class that you were present.

If you miss class time, it is your responsibility to get the material that you missed from your classmates; you should also make sure that you ask if there were any important announcements. If you miss an entire class, you should—at a minimum—arrange to copy notes from a classmate. You may also arrange to sit in on another instructor’s lecture with permission from that instructor.

Pay attention. Lecturing will take place in both the lecture and laboratory classrooms.

Listen carefully. Take clear notes in phrase form (don’t try to write complete sentences). Consider using a tape recorder to tape lectures (ask your instructor for permission first). Keep at it; taking good notes is a skill that you will get better at over time.

Respect others in the class. If you’re talking, texting, giggling or snoring, it’s harder for everyone else in the class to pay attention. It’s also harder for the instructor to keep the flow of explanation. If you must come to class late (or need to leave early), choose a seat that causes the least disruption to the class.

Know important dates. Do not rely on your instructor to remind you of upcoming exams and important deadlines. Knowing these dates is your responsibility. You should know the dates of your exams, deadlines for other assignments, drop deadlines, and any class dates that have been rescheduled on a non-scheduled day (i.e. Friday classes being give on a Tuesday).

Keep track of your grades. Record your grades in this handout. Calculate your average every couple of weeks to see how you’re doing. Ask your instructor if you aren’t sure. If your grade comes as a surprise to you at the end of the semester, it’s your fault.

Work hard outside of class. This is perhaps the most important factor relating to your

success in the class. As much as possible, minimize other time commitments in your life. Keep in mind that for a 3-hour lecture, instructors spend (on average) 6-9 hours outside of class preparing—and they already know the material. How much time should you spend? Consider doing some or all of the following, but rest assured that if you do nothing outside of class, you will have wasted a semester of A&P. a. Within 24 hours of class, review or rewrite your notes being sure to fill in any missing information and correct any misspelled words. As you re-write your notes, pay attention to when something is confusing. Write your question(s) in your notes and leave space to answer it later when you come back to your notes.

Then make sure that you either look in your book, or on the internet, or ask your instructor. b. Watch the videos and animations that are on the CD that comes with your textbook. These often help to illustrate some of the more complicated concepts in the course. Look for websites online that explain the topics that were covered in class. Sometimes hearing or seeing something explained another way will help you remember it. c. Form study groups. Numerous studies have shown that we learn best by explaining concepts to someone else.

These same studies frequently show improvements of 20% or more on grade averages for students that learn in groups. Don’t be embarrassed to form a group because you think you’re weak, and don’t think that you won’t benefit from group study because you’re a strong student. Groups help everyone. d. Quiz yourself. Quiz your classmates.

Use study questions from the lecture guides, use online and CD quizzes, copy diagrams with the labels covered up, answer questions from the back of the book. The more active you are, the better your brain will learn it. Don’t just re-read your notes.

17

e. Play to your strengths. Figure out your learning styles or preferences (see page 14).

Try to incorporate those preferences into how you study. Try various ways of exposing yourself to the information. Consider using a tape recorder to record lectures or make study sheets or flash cards to take out every time you’re sitting still for more than a few minutes (like on the train or bus).

8. Do your own work. While it certainly helps to study with others, relying on someone else’s notes won’t help you much at all— even if the notes are from your instructor.

Your brain learns by doing.

9. Don’t fall behind. Don’t wait to get started until week 2 or 3 just because it doesn’t seem like a lot of material at first. If something is unclear, ask a question. If you’re struggling, don’t be embarrassed— ask for help early. If you wait too long, it

may be too late. You should talk to your instructor if you’re having a very hard time, but you can also try the following: a. Learning Resource Center is located on the first floor of Sage Hall (behind Meister Hall).

It has videos and CD-ROMs for all of the major concepts covered in A&P. Some tutoring is also available. b. Biology Study Lab is in Meister 418 and is stocked with models, slides and microscopes, and computers. Tutors are available, and many of your instructors volunteer to spend time in the study lab to provide extra help.

Hours are usually posted during the second week of the semester.

10. Give feedback to your instructor(s). If there is anything your instructor can do to help you succeed in the course, or to improve the course, please bring it to his or her attention. We value and depend on your constant feedback to make this course the best that it can be for all of our students.

A: Yes. Go to http://www.coursesmart.com/0077676653 to rent ebook. It allows you to search, highlight, copy/paste, print, etc. The subscription lasts one year. See the website above for more info.

Q: What are the Bio24 prerequisites?

A: Bio23. We also highly recommend taking Bio24 only if you have C+ or higher grade in Bio23.

Q: Is the textbook available at the library?

Yes. There are a few textbooks available at the library on reserve.

Also, you can obtain the first three chapters and the atlas through electronic reserves at http://tiny.cc/eRatBCC

Q: Can I take both Bio23 and Bio24 together?

A: No. COURSE MATERIAL AND LAB MANUAL

GRADES Q: Where can I get the Course Guide and Lab Manual from?

A: (1) Download it from Electronic Reserves at the BCC Library Website http://tiny.cc/eRatBCC OR (2) Download it from the A&P online course companion http://tiny.cc/B2324CG

Q: How do I calculate my overall grade?

A: You can calculate your grade using the formula below. The formula uses a 0-100 grade scale.

Double check with your instructor about minor changes in his/her lab grade breakdown. Adjust the formula to your instructor grading breakdown.

Overall Grade = Lab Grade x 0.4 + Lecture Grade x 0.6 Lecture Grade = (E1 + E2 + E3 + E4 + Final) / 5 Note that final exam will count twice by replacing the lowest/absent lecture exam grade.

Lab Grade = Midterm x 0.30 + Final x 0.30 + Quizzes x 0.40

TEXTBOOK Q: Can I use an older version of Saladin 7th Edition?

A: Yes. Just be aware that when your instructor refers to pages or figures in the 7th edition, they might differ from yours.

See BCC Grading system http://tiny.cc/BCCGrading

Q: Can I use a different textbook (other author’s)?

A: Yes, but double check with your instructor. There is a free textbook available at http://tiny.cc/OpenETxtbook

at

Q: Why no one told me about my grade until the end of the semester?

A: Because it is your responsibility to keep track of your grades. You should ask your instructor for clarification at the BEGINNING of the semester, not at the end, when it might be too late to plan for changes. See how to calculate your grade above.

Q: Where can I purchase the textbook?

A: The hardcopy of the textbook is available at the BCC bookstore, and at many online stores. The BCC bookstore also has a lose-leaf version, which

Q: What is the passing grade?

24

A: Like most courses at BCC, the passing grade is 60 (D-). HOWEVER, many programs at BCC (e.g.

Nursing, Radiology, and Nuclear Medicine) require a C+ or higher to be accepted into the program.

exam and failing the course will receive an automatic grade of F in the course.

Q: How do I get a W in the course?

A: To receive a grade of W students must officially withdraw from class between the 3rd and 10th week, by filing an online withdrawal form (via CUNYFirst). Neither the Department nor your instructor can assign or change your grade to a W.

Q: I don't want a C grade or lower, can the professor give me an F? A: No. The professor cannot manipulate your grade. You will only get an F in the course if your grades average below 60. A very low grade in the lecture final exam will very likely bring your grade average to an F.

ATTENDANCE/LATENESS Q: Is attendance mandatory?

A: Yes. Students with an excessive absence record will receive an automatic F in the course. The Department defines excessive absence as having missed more than three scheduled classes.

Q: I got my Midterm Grade‌can I still get a C+?!

A: Here is a rule of thumb: If your Midterm Grade is 70, then you need to get AT LEAST 84 in ALL the remaining assignments (Lecture Exam 3, Lecture Exam 4, Lecture Final, Lab Quizzes, Lab Final and any other assignment your instructor gives you). Doable, but you need to significantly increase the amount of time you spend studying and reviewing in an effective way.

If your Midterm Grade is 65, then you need to get AT LEAST 89 in ALL the remaining assignments (Lecture Exam 3, Lecture Exam 4, Lecture Final, Lab Quizzes, Lab Final and any other assignment).

Highly unlikely to happen. Almost no one makes it If your Midterm Grade is 60, then you need to get AT LEAST 94 in ALL the remaining assignments (Lecture Exam 3, Lecture Exam 4, Lecture Final, Lab Quizzes, Lab Final and any other assignment).

Almost impossible

Q: What about lateness?

A: Instructors have the right to mark students absent if (1) students arrive 15 or more minutes late on three occasions, and/or (2) students leave 15 or more minutes early before the class ends.

LAB MIDTERM and LAB FINAL Q: When is the lab midterm/lab final?

A: You can find the dates on the calendar in the handout given to you the first week of classes, in the A&P Bulletin Board on the 4th floor of Meister Hall, and in the A&P website. Lab Midterm is the 7th week of classes, and lab final the 14th.

Q: If I missed a lab, can I go to another section taught by another professor to make it up?

A: This is up to your instructor. It also depends on availability of space on other lab section, and the willingness of other instructor to let you sit in her/his lab. Consult with you instructor.

Q: Can I get an incomplete (INC) in the course?

A: An INC grade is only assigned to students who miss the course final exam AND are otherwise passing the course AND have an excused absence approved by the instructor from the course final exam. Students have until the 10th week of the following semester to resolve the INC grade.

Q: Can I drop the lab midterm or the lab final?

A: No

Q: How did I end up with an F in the course!!!?

A: You fail the course if you have an average below 60. In addition to students who academically fail the course (1) Students who attend at least two class periods but unofficially stop attending will receive an automatic grade of F in the course, or (2) Students who are absent from any course final

Q: Can I make up the lab midterm or the lab final?

A: No. Consult your professor in case of an emergency. You’ll need to document the reason of your absence.

LECTURE FINAL EXAM 25

A: Because this is the Bio23/24 policy, which might or might not coincide with other courses/departments policies.

Q: Is the lecture final exam cumulative?

A: Yes. This means that the final covers ALL the topics seen during the entire semester (i.e. first class to last class).

SWITCHING SECTIONS

Q: I have to travel during finals; can I make up the final?

A: No. The week of finals is posted in the CUNY academic calendar website (http://www.cuny.edu/academics/calendars.html) more than one year in advance. You should be able to plan well in advance. Consult your professor in case of an emergency. You’ll need to document the reason of your absence.

Q: Can I switch sections?

A: No

Q: Can I make up the lecture final exam?

A: No. Only in the case of a well documented emergency you might qualify for an incomplete grade (INC). An INC grade is only assigned to students who miss the course final exam AND are otherwise passing the course AND have an instructor approved excused absence from the course final exam. Students have until the 11th week of the following semester to resolve and INC grade. Consult with you instructor.

Q: Are instructors required to provide handouts?

A: No. It is up to each instructor’s criterion, style, and pedagogic philosophy.

Q: Can I drop the lecture final exam?

A: No

Q: Is it better to take Anatomy and Physiology during the summer or during the regular academic semester?

A: This depends on your schedule and the amount of time you have to designate for study and review.

You should be aware that the summer course moves at a faster pace as opposed to the fall/spring course, so you must be certain that your schedule will allow you adequate time to prepare.

Additionally, you should speak with a Biology professor to determine which will work best for you.

You can think it his way: Fall/Spring sessions are like a full time job. Summer sessions are like a full time job with plenty of overtime, think summer equals two full time jobs.

Q: Why not?

A: Because this is a Biological Sciences Department policy.

HANDOUTS AND RETURNED EXAMS AND QUIZZES

Q: Are instructors required to give exams back?

A: No. It is up to each instructor’s criterion, style, and pedagogic philosophy.

SUMMER SESSION SESSIONS

LECTURE EXAM MAKEUPS Q: Can I make up the lecture exam?

A: No. If you know in advance you will be missing an exam, tell your professor. (S)he might allow you to take it in advance. Consult with you instructor.

EXTRA CREDIT Q: Can I do an extra credit assignment to raise my grade?

A: No. There are no extra credit assignments in Bio23/Bio24.

Q: My other professor in the other department let me do extra credit assignments, why can’t I do it in Bio23/24?

vs.

FALL/SPRING

STUDYING FOR A&P Q: How much should I study to get a C+ in the course?

26

A: This is a hard one to answer. There is no onsize-fits-all rule. However, just as a guideline you can use this rule of thumb: You need to study at least 18 hours a week. More if you have no science background and don’t feel comfortable with A&P, less if you really like A&P and have some background in the sciences. See under “Student Responsibilities” in the Study Guide and Lab Manual for a more comprehensive advice.

Q: What should I do if I feel overwhelmed by the workload of A&P? A: Speak to your professor immediately if you begin to feel that the workload is overwhelming. In some cases, time management and alterations to your schedule may be necessary to free up enough time for the course work.

Q: Where can I get help?

A: Talk to your professor and go to your professor’s office hours. You can also go to see the tutors at the Biology Study Lab (ME418). The Study Lab counts with tutors that can help you. The Study Lab has CD-Roms with tutorials, computers with internet access, and many of the models and slides you use in the lab component of the courses.

Study Lab hours are posted on the doors of the 4th floor rooms. The study lab opens after the second week of classes.

Q: Is understanding the scientific/medical terminology necessary to do well in the course?

A: Absolutely! Mastery of vocabulary and terminology will provide you with greater understanding of the material you read and are exposed to in class lectures. You can reference the glossary and the lexicon in the back of the textbook or utilize additional resources, such as a medical dictionary or an online encyclopedia, to learn the terminology.

Q: Can I use outside sources to supplement the A&P required textbook?

A: Yes. Just be sure that the outside resources, including websites, are credible and have correct information (e.g. usually dot edu sites). If you are not certain, just ask your instructor. Also, focus on just a couple of resources (e.g. a textbook, a website you find helpful, and your notes). If you diversify a lot you will lose focus and get easily overwhelmed.

Q: What about help with technical problems?

A: Check the Technology Service Center (ex-Help Desk) 718.289.5970; Roscoe Brown [RB], Room 308; http://tiny.cc/TSCatBCC Q: I have a question not answered above, where do I go for help?

A: Ask you professor. If (s)he doesn’t know, (s)he can find out for you, or direct you to where to look for the answer.

HELP!

B. Identification of Major Vessels (45 min) You have already labeled all of the vessels that you are responsible for knowing in this course (Pre-Lab Activity C), but it isn’t enough to simply memorize the diagrams in your textbook—you need to know where each vessel is carrying blood from and where it is carrying blood to. Fortunately, arteries and veins almost always exist in pairs. One vessel will deliver blood from the heart to the organ or region (artery) and the other will deliver blood from the organ or region to the heart (vein).

1. Fill in the table below by indicating the organ, region or vessel that the named vessel receives blood from, and the organ, region or vessel to which it delivers blood (see example for aorta and coronary arteries). If you’re doing it right, both columns will have the same answer. You will need to refer to the images in your textbook and lab models to do this.

Lab Activities The following is a copy of the pages found in the LtLabStation© activities to be performed during lab A. Heart, ECG, and Pulse Lesson (60 min) 1/8 – Lesson Learning Objectives In this lab, you will record and analyze your own ECG and finger pulse, and observe how these provide different representations of the cardiac cycle.

Learning objectives By the end of this lab you will be able to do the following: • Record an ECG and identify the major components.

• Explain the temporal relationship between the ECG and the finger pulse.

• Interpret events in the cardiac cycle, and relate these to features in the ECG and the finger pulse.

2/8 - What is an ECG? The electrical currents along the heart walls travel through the body and generate changes in the electrical potential of the skin. These changes of potential can be detected by applying electrodes (leads) to the skin (typically wrists, ankles and six location in the heart) and recorded in an Electrocardiogram (ECG or EKG) Figure 1.

3/8 - What is Pulse?

When the left ventricle ejects blood into the aorta, this generates a pressure wave that travels along systemic arteries. The elastic arteries walls expand and recoil at a frequency that follows heartbeats. The rhythmic contraction and recoil of the arteries is known as the pulse.

Activity. Using your index and middle fingers, apply light pressure to a pulse point. Record pulses in the table below Subject Pulse

4. Based on your observations, what phase is faster: systole or diastole? Why? 8/8 – Report B. Blood Pressure Lesson (90 min) 1/10 - Blood Pressure In this lab you will become familiar with auscultation of Korotkoff sounds in the measurement of blood pressure. The activities involve measuring your blood pressure using a blood pressure cuff, a sphygmomanometer, and one of the following: a stethoscope, cardio microphone, or finger pulse transducer.

You will also assess how changes in arm position affect measured blood pressure.

Learning objectives By the end of this lab you will be able to do the following: • Explain what is meant by systolic blood pressure and diastolic blood pressure.

• Use a sphygmomanometer and stethoscope to measure human arterial blood pressure.

• Demonstrate how measurement position affects the magnitude of the arterial blood pressure.

Figure 1. Indirect measurement of arterial blood pressure.

- 62 -

2/10 – Auscultation In this activity you will measure blood pressure and listen for Korotkoff sounds using a stethoscope.

Don't leave the cuff inflated at high pressures for too long, for the following reasons: • Pressures greater than the volunteer's systolic pressure will prevent blood flowing below the cuff.

• Pressures between the volunteer's systolic and diastolic pressure will hinder the return of the venous blood to the heart.

• Always deflate the cuff completely after you have determined the volunteer's diastolic pressure.

Clinically, it is recommended that blood pressure measurements are made without clothing obstructing the cuff. View the correct way to perform a blood pressure measurement clinically.

Palpation procedure Here you will palpate the pulse to estimate systolic blood pressure.

1. Wrap the sphygmomanometer cuff around the volunteer's upper arm, and just above the elbow.

Ensure that the cuff fits firmly and is not loose.

2. Feel for the brachial or radial pulse, then inflate the cuff until the pulse is no longer detectable.

3. The pressure on the sphygmomanometer when the pulse is no longer detectable is an estimate of the systolic blood pressure.

4. Enter this value in the table below.

5. Deflate the cuff.

The "palpatory" estimation of systolic blood pressure can be very useful when auscultatory sounds are difficult to distinguish. For example, patients who are in shock, pregnant, or following exercise.

Estimated systolic blood pressure using palpation Volunteer's Name Systolic Pressure (mmHg)

Stethoscope procedure You will now record the systolic and diastolic blood pressure as you listen to the Korotkoff sounds. To perform this correctly, you must be familiar with the use of a stethoscope and sphygmomanometer.

1. Place the stethoscope diaphragm over the brachial artery. Inflate the cuff to 30 mmHg higher than the estimated systolic pressure (see the table above).

2. Slowly reduce the pressure in the cuff (~1–2 mmHg/s) while listening through the stethoscope for Korotkoff sounds.

3. The systolic pressure is the pressure at which sharp, tapping sounds are first heard.

4. Continue to slowly reduce the cuff pressure. The diastolic pressure is defined as the pressure at which the sounds disappear.

5. Completely deflate the cuff after diastolic pressure is determined. Never leave the cuff inflated, or partially inflated.

- 63 -

6. For each volunteer, record two measurements of the blood pressure. Allow 1–2 minutes between measurements for recovery.

Blood pressure using stethoscope method: Volunteer's Name Attempt Systolic Diastolic Pressure Pressure (mmHg) (mmHg) 1 2 1 2 Check your understanding 1. What are some possible sources of error or variation in this technique of blood pressure measurement?

2. Is the following statement true or false? Clinically, two careful measurements of blood pressure with a one-minute interval are recommended. A repeat measurement should be taken when there is any uncertainty.

3/10 - Equipment setup Setup In the next activity you will measure the volunteer's blood pressure using a finger pulse transducer.

1. Connect the pressure transducer to Input 1 on the PowerLab. 2. Ensure the pressure transducer is attached to the sphygmomanometer cuff.

3. Wrap the sphygmomanometer cuff around the upper arm of your volunteer, just above the elbow.

4. Connect the finger pulse transducer to Input 2.

5. Place the pressure pad of the finger pulse transducer against the distal segment (the tip) of the middle finger of the volunteer's hand (on the same arm as the blood pressure cuff).

6. Use the Velcro strap to attach it firmly, neither too loose nor too tight.

4/10 -Blood pressure and finger pulse In this activity you will investigate the changes in finger pulse while measuring blood pressure.

Procedure 1. Use the same volunteer as in the previous activity.

2. The volunteer should relax with hands in the lap, and sit as still as possible to minimize movement artifacts.

3. Select Start to record. Enter the volunteer's name into the Comment panel, then select Add. The recorded pulse should look similar to this example.

- 64 -

4. Inflate the cuff to 30 mmHg higher than the estimated systolic pressure (see the table below, for your reference). Note that the finger pulse signal disappears.

5. Enter "arm at heart level" into the Comment panel, then select Add. 6. Slowly deflate the cuff at a rate of 1–2 mmHg/s. Note where the finger pulse signal reappears.

7. Deflate the cuff completely after the pressure falls below 50 mmHg, and select Stop.

8. Now repeat the procedure with the arm above the head. Select Start to record, inflate the cuff to 30 mmHg above systolic, then allow the pressure to decrease slowly.

9. Enter "arm above head" into the Comment panel, then select Add. 10. Deflate the cuff completely after the pressure has fallen below 50 mmHg, and select Stop.

The table below shows your estimate of the volunteers' systolic blood pressure from the pulse palpation activity.

Estimated systolic blood pressure using palpation Volunteer's Name

Systolic Pressure (mmHg)

5/10 - Blood pressure and finger pulse As the cuff pressure is released, does the reappearance of the finger pulse indicate your volunteer's blood pressure?

Pulse Detection Method Analysis 1. Scroll to the comment "arm at heart level".

2. Place the point selector on the first clear pulse to reappear as the cuff pressure was decreasing. This represents the return of blood flow to the forearm, which occurs at the systolic pressure.

3. Enter the value from the Pressure channel into the table.

4. Enter "systolic pressure" into the Comment panel, then select Add at this point in the data panel.

5. Repeat steps 1–4 for the comment "arm above head".

Pulse Detection Method Estimated Systolic Pressure (mmHg) Arm at heart level Arm above head

Check your understanding 1. From your finger pulse recording, is there any way to determine diastolic pressure? Could a finger pulse measurement ever replace the stethoscope in determining diastolic pressure?

- 65 -

2. What happened to the finger pulse amplitude when the arm is held above the head? What happened to the estimated systolic pressure? What do you think could account for this observation?

6/10- Cardio microphone In the auscultatory measurement of blood pressure, the Korotkoff sounds will be heard as the blood pressure cuff is deflated (if you use a stethoscope). you will find in the following activities, the Korotkoff sounds can also be seen as spikes (if you a cardio microphone and a PowerLab).

The Korotkoff sounds will appear as spikes on the Cardio Microphone channel, as shown in the image below (orange signal). The upper channel (dark blue signal) shows the corresponding pressure in the cuff it is deflated.

Activity: Label the diagram on the right with the appropriate terms: Auscultatory gap, Diastolic pressure, Systolic pressure.

7/10 - Equipment setup Setup 1. Leave the pressure transducer connected to Input 1 of the PowerLab. 2. Ensure the pressure transducer is attached to the sphygmomanometer cuff.

3. Wrap the sphygmomanometer cuff around the upper arm of your volunteer, just above the elbow.

4. Remove the pulse transducer from Input 2.

5. Connect the cardio microphone to Input 2. In the following activities you will place the cardio microphone over the brachial artery. Note: the side of the cardio microphone with the hole in it should be placed next to the skin You should locate the brachial artery by palpation. It lies slightly medial to the tendon of the biceps muscle just above the elbow. If it lies below the level of the cuff you should use a Velcro strap to secure the cardio microphone over the artery. If it lies conveniently beneath the cuff you can use the cuff to hold the cardio microphone in place over the volunteer's brachial artery.

- 66 -

8/10 - Cardio microphone In this activity you will use the cardio microphone to record arterial sound while recording blood pressure.

Procedure Try to keep room noise to a minimum in these activities to avoid a noisy recording from the cardio microphone.

1. Ensure the cardio microphone is positioned over the brachial artery and held in place with a Velcro strap.

2. Select Start to record.

3. Inflate the cuff to 30 mmHg higher than the estimated systolic pressure.

4. Slowly reduce the pressure in the cuff (~2–3 mmHg/s).

5. Deflate the cuff completely after the pressure has fallen below 50 mmHg or after the disappearance of the Korotkoff sounds. Enter "slow" into the Comment panel, then select Add. 6. Select Stop.

7. Allow 1–2 minutes for recovery.

8. Repeat the procedure on the same volunteer, but modify the speed at which you release the pressure in the cuff. Enter "medium" and "fast" into the Comment panel, and select Add when deflating at the respective speeds.

The table below shows your estimate of the volunteers' systolic blood pressure from the pulse palpation activity.

Analysis Scroll to the comment "slow".

1. Place the point selector on the first Korotkoff sound (the first clear spike in the series).

2. Enter the value from the Pressure channel into the table (this is the systolic pressure).

3. Place the point selector on the last clear spike in the series.

4. Enter the value from the Pressure channel into the table (this is the diastolic pressure). Note: diastole may be hard to detect. Sometimes you need to estimate by extrapolating the trend of the decreasing spikes.

Check your understanding 1. What is the basis for the sounds referred to as Korotkoff sounds?  Laminar blood flow  Maximal blood flow  Turbulent blood flow 2. How did deflating the cuff more quickly alter your blood pressure measurements? Can you explain why?

10/10 -Report C. Optional: The Cardiac Cycle 1. For each event that leads to the flow of blood through the heart, the following must occur in order: ➢ electrical stimulation (depolarization of the myocytes) ➢ contraction (decreases the volume of the chamber) ➢ pressure increases ➢ valve opens ➢ blood flows ➢ relaxation (increases the volume of the chamber) ➢ pressure decreases ➢ valve closes (to prevent blood from flowing back into the chamber) One important thing to keep in mind: the events of the cardiac cycle do not take into consideration where the blood is going after it leaves the heart. Therefore, we don’t need to treat the left and right sides of the heart differently. We don’t even need to consider them at all since the left and rights sides of the heart beat at the same time.

Write out all of the steps for all of the stages of the cardiac cycle. Use the bullet points above and the diagram to the right to help guide you. Start with the first steps given below: The SA node fires and the atria become depolarized (electrical event).

The atria contract which decreases the volume of the chambers (contraction event). …

You can practice identifying WBCs on your own using online histology tutorial (e.g. http://www.mhhe.com/biosci/ap/histology_mh/start_histology.html) D. Analyze An Abnormal Complete Blood Count (CBC; 15 Min) CBC values vary by age and sex. Normal values are determined by the laboratory where the test is performed. Compare the patient’s values to the normal range reported (use the column on the right), then answer the questions that follow. Assume that your patient is a 24 year-old woman who is not pregnant.

1. Why is “normal” presented as a range instead of an exact number?

2. Your patient has a platelet count of 263,000 per µl, should we be concerned? Why or why not?

3. Cell numbers are often reported as percentages as well as actual numbers (like in the report above), but when one cell type has an abnormally high or low number, it changes the percentages of all blood cell types. Therefore, when looking for abnormal counts, you should always use the actual number—not the percentage. Which cell type or count is most abnormal in the test above?

- 73 -

4. What type of pathogen does the abnormal cell type normally respond to? What kind of pathogen do you think your patient is trying to fight off?

5. Predict what a blood test would look like for someone with lymphocytic leukemia.

E. Blood Antigens And Antibodies (15 Min) 1. Review antigen and the different kinds of antigens on red blood cells, antibody, and agglutination from Pre-lab Activity D. 2. In the table below, draw the appropriate antigens on each of the red blood cells. You can simply use the letter of the antigen as the A+ example shows (use the letter D to symbolize the presence of the Rh factor).

A+ B+ AB+ O+ A D A-

B-

- 74 -

1. Follow the instructions below for a simulated blood typing test done with chemicals, not real blood.

Procedure You’ll work in groups of 3-4 to do this activity. Each group will get four blood typing slides and eight toothpicks. Each table will share “blood” samples and anti-serum.

There are four unknown “blood” samples: • Mr. Smith • Ms. Jones • Mr. Green • Ms. Brown There are three kinds of antibodies: ✓ anti-A simulated typing serum ✓ anti-B simulated typing serum ✓ anti-Rh simulated typing serum Directions Use a wax pencil to label each of your slides with the name or number of the patient that you will be testing. i. Add “blood” samples to appropriate slides. ii. Place 3-4 drops of Mr. Smith’s blood in each of the A, B, and Rh wells of slide 1. iii. Place 3-4 drops of Ms. Jones’ blood in each of the A, B, and Rh wells of slide 2. iv. Place 3-4 drops of Mr. Green’s blood in each of the A, B, and Rh wells of slide 3. v. Place 3-4 drops of Ms. Brown’s blood in each of the A, B, and Rh wells of slide 4. vi. Add antibodies to appropriate wells on each slide. vii. Place 3-4 drops of anti-A simulated typing serum in each A well on the four slides. viii. Place 3-4 drops of anti-B simulated typing serum in each B well on the four slides. ix. Place 3-4 drops of anti-Rh simulated typing serum in each Rh well on the four slides. x. Use separate toothpicks to stir each sample. xi. Record your observations in the table below (simply note whether you saw clumping or not, then decide what the blood type must be). Note: a positive test is indicated by a strong agglutination reaction. anti-A serum

anti-B serum

anti-D serum (Rh)

Blood Type

Mr. Smith Ms. Jones Mr. Green Ms. Brown

2. Now answer the following questions: a. You’ve just determined someone’s blood type to be AB-. What antigens are present on their RBCs?

- 75 -

b. You perform a blood typing test in which anti-A and anti-Rh both cause agglutination. What is the blood type? c. You perform a blood typing test in which none of the antibodies cause agglutination. What is the blood type?

G. Blood antibodies (10 min) Antibodies are useful for a blood test, but if agglutination occurs in our bodies, it is a real problem.

In infancy, we begin to produce antibodies to bacteria that naturally inhabit our intestines.

Interestingly, these antibodies also agglutinate the ABO antigens on our RBCs. Obviously, this would be a bad thing if we produced antibodies that caused our own RBCs to clump, so for that reason, we only make the antibodies that won’t hurt us. For instance, someone with Type A blood wouldn’t be able to tolerate anti-A antibodies, so she would only have anti-B, not anti-A. Interestingly, we don’t make antibodies to the Rh factor unless we are directly exposed to blood containing that antigen. So, for now, we only have to worry about anti-A and anti-B antibodies.

1. Use the information above to help you fill out the table below showing which antibodies will be found in the plasma of the different blood types.

Blood type A+ B+ AB+ O+ ABABOAntigens present on RBC surface Antibodies present in plasma

A, Rh

anti-B

H. Blood Transfusions (20 min) Now that you see that we have both blood antigens and antibodies to worry about, you can no doubt imagine why it is so important to find the right match before performing a blood transfusion. Luckily, we only have to worry about the antibodies that the patient (the one receiving the blood) has in his or her plasma. It’s not important to think about the antibodies in the donor’s blood in this case.

Let’s take the case of a patient, Erica, who has lost a great deal of blood and needs a transfusion. Her blood type is A- but the hospital is completely out of A- (which would be the best option) blood for transfusions, so we have to find a substitute.

1. Start by identifying the antigens and antibodies in the patient’s blood, and draw them like this: A anti-B

A+

B+

AB +

O+

A-

B-

AB -

O-

2. Now draw all of the other blood types in the circles above (don’t worry about the antibodies, just draw the antigens). These represent all of our possible donors.

- 76 -

The first rule of thumb is that we never want to give Rh+ blood to someone who is Rh-. It’s true that they probably don’t have antibodies to the Rh factor, but if we give them that blood, they will begin to make antibodies, and that will cause problems in the future. So we can just eliminate half of the donors in this case.

Now all we have to focus on is whether there is a dangerous match between the antibodies in the patient and the antigen on the surface of the donor cell. Let’s look at the B- donor. What would happen if the B antigen on the donor cell were exposed to the patient’s plasma (containing anti-B)?

Agglutination. And that’s not good, so that’s a bad match. Try the other blood types to see if you can find a match. Tip: if the match is no good, put an X through that donor cell so you don’t lose track.

3. What’s the only blood type that we can give our A- patient if we don’t have any A- blood?

Now try this one: Mary has been in an accident and is losing a great deal of blood from damage to her femoral artery.

Paramedics arrive in time to rush Mary to the closest Emergency Room. The attending medical team determines Mary’s blood group to be O positive.

4. Why should Mary not be given type A+ blood?

5. What is the correct blood group match for Mary? Why?

I. Erythroblastosis Fetalis Or Hemolytic Disease Of The Newborn (HDN; 15 Min) Although people with Rh-blood don’t normally make antibodies to the Rh factor, any exchange of blood with someone who is Rh+ will cause them to make antibodies. Erythroblastosis fetalis results from a related complication. Work through the following questions to see that you understand what causes it.

Theresa and John and thrilled to learn that they are to be parents for the first time. Theresa goes in for her routine pre-natal check up and finds that her blood type is O negative, but John has Rh positive blood, so there is a chance that their child will be Rh positive. For the following questions, assume that the fetus is Rh positive.

1. When will Theresa first be exposed to Rh antigens? Be specific.

2. When will she produce anti-Rh antibodies? Be specific.

3. Will her first child be affected by anti-Rh antibodies? Why or why not?

- 77 -

4. If Theresa isn’t given an immunoglobulin shot (RhoGAM), can she and John safely have a second child? Why or why not? (Include HDN in your explanation).

5. What is RhoGAM? How does it prevent Hemolytic Disease of the Newborn (HDN)?

Lab 6 – The Respiratory System: Spirometry

Akkaraju, Liachovitzky, & McDaniel 2014/15 Experiment by Wolf & Liachovitzky 2014/15

Objectives Checklist - After completion of this lab, you should be able to:  describe the mechanics of ventilation:  differentiate between static pulmonary changes in volume, pressure and flow tests and dynamic pulmonary function tests  identify the muscles involved in ventilation; distinguish those involved in  perform pulmonary function tests, and inspiration from those involved in describe the common measurements expiration. made from them (PIF, PEF, FVC and FEV1).  distinguish between inspiration & expiration and resting & forced breathing  distinguish between restrictive and in terms of energy requirements obstructive lung disorders  define the various respiratory volumes  describe the effect of airway restrictions and capacities. on PIF, PEF, FVC and FEV1

Pre-Lab Activities A. Ventilation 1. Look at the diagram to the right showing the position of the relaxed diaphragm relative to the ribcage, Demonstrate where the relaxed diaphragm is on your own body. Where will the diaphragm will be when it is contracted?

2. If the diaphragm were to contract, i. what would happen to the volume (space) of your thoracic cavity (increase/decrease)? __________ ii. what would happen to the pressure (increase/decrease)? __________ iii. which way will the air flow (inward/outward)? __________ 3. If the diaphragm were to relax, iv. what would happen to the volume (space) of your thoracic cavity (increase/decrease)? __________ v. what would happen to the pressure (increase/decrease)? __________ vi. which way will the air flow (inward//outward)? __________ 4. Based on your answers to the previous two questions, and the fact that muscle contraction requires ATP, what can you say about the energy requirements of inspiration and expiration (normal quiet breathing using only the diaphragm)? Is inspiration active or passive? What about expiration?

• Inspiration: • Expiration: 5. Under conditions where normal breathing isn’t sufficient, other muscles will assist the diaphragm in changing the volume of the thoracic cavity. A muscle that increases the volume of the thoracic cavity will cause pressure to ( / ) which means that it is helping with forced (inspiration/expiration).

Lab Activities The following is a copy of the pages found in the LtLabStation© activities to be performed during lab A. Lung Volumes Lesson 1/16 – Introduction In this lab, you will record and analyze your own respiratory variables, and mimic the situation of a patient who breathes with hyperinflated lungs.

Learning objectives By the end of this lab you will be able to do the following: • Record and analyze your own respiratory variables.

• Relate your recorded lung volumes and capacities to those of a typical person of the same sex, height, and age.

• Perform pulmonary function tests, and analyse dynamic variables from your volunteer's data.

• Appreciate how it feels to breathe with hyperinflated lungs.

2/16 - Pulmonary function tests Pulmonary function tests (or measurements) can be classified as either static or dynamic. Before proceeding with this lab, check that you know the difference between these tests.

1. Place each of the measures below into either the static or dynamic category.

2. How did you make the distinction between the two types of test?

3/16 - Equipment setup Setup 1. Connect the Spirometer Pod to Input 1 on the PowerLab.

- 88 -

2. The Spirometer Pod is sensitive to temperature and tends to drift during warm-up. To prevent this, turn on the PowerLab at least 5 minutes before use.

Then place the Spirometer Pod on a shelf or beside the PowerLab, away from the PowerLab power supply.

3. Connect the two plastic tubes from the flow head to the short pipes on the back of the Spirometer Pod. 4. Attach clean-bore tubing, a filter, and a mouthpiece to the flow head.

5. Make sure you have extra mouthpieces and disposable air filters for each volunteer. Also, make sure to have a tape measure for measuring the volunteer's height.

NOTE: If you are suffering from a respiratory infection, do not volunteer for this experiment.

4/16 - Zeroing the Spirometer Pod The Spirometer Pod is susceptible to thermal drift of the baseline signal. However, the baseline can be reset by selecting the Zero Inputs button before making any new recording.

NOTE: It can be difficult to breathe normally when you are consciously thinking about it. It is essential that the volunteer sits comfortably in a position from which the computer screen can't be seen.

Ensure tubing always points upwards.

Procedure 1. Leave the flow head apparatus undisturbed on the bench and select Zero Inputs. This will reset the offset of the Flow channel to zero.

2. Ask the volunteer to put on the nose clip. If possible, leave the nose clip on for the entire lab to promote breathing through the mouth. This ensures that all air breathed passes through the mouthpiece, filter, and flow head.

To calculate volume from the flow, start recording before breathing through the flow head.

3. Select Start to record. The mouthpiece can now be put into the volunteer's mouth.

4. Hold the flow head with two hands with the plastic tubing pointed upwards.

- 89 -

5. Observe the data. Select Auto Scale if required. Expiration should be a downward deflection. If the signal deflects upward stop recording and swap the tubular connections on either the back of the Spirometer Pod or the flow head.

6. When the volunteer has become accustomed to the apparatus, select Stop.

Make sure the volunteer keeps the nose clip on and breathes through the mouthpiece.

5/16 - Volume correction The volume correction procedure corrects for the fact that expired air is of a greater volume than inspired air. This is due to expired air being warmer and containing more water vapor.

Procedure Zeroing 1. Re-zero the Spirometer Pod using the Zero Inputs button.

Remember that the flow head must be left undisturbed on the bench during the zeroing process.

2. Select Start before you ask the volunteer to pick up the flow head and start breathing through it.

3. The volunteer should remain in the same setup as on the previous page.

4. Ask the volunteer to inhale and exhale normally through the apparatus. That is, normal tidal breathing for 1 minute.

5. Enter "volume correction procedure" into the Comment panel, then select Add. 6. At the end of 1 minute, select Stop. The volunteer should continue breathing through the flow head and keep the nose clip on.

Volume correction 7. Use the compression buttons and scroll bar to view the normal tidal breathing.

8. Use the region selector to select the regular breathing data. Do not select the areas of zero flow at the beginning and end of the recording.

9. In the Spirometry panel, select Calibrate. This will apply a volume correction to your data.

6/16 - Static measurements Challenge 1. Match the lung parameter to its correct description.

- 90 -

2. Place each label onto its correct location

7/16 - Static measurements The question here is: "What lung volumes and capacities can be measured, and how can these measurements be made?"

Your data from the previous activity has been transferred to this page. Therefore, you do not need to perform the volume correction procedure.

Procedure

- 91 -

1. Re-zero the Spirometer Pod using the Zero Inputs button. Remember, the flow head must be left undisturbed on the bench during the zeroing process.

2. Ask the volunteer to hold the flow head with the tubes pointed upwards.

3. Select Start to record.

4. Enter "normal tidal breathing" into the Comment panel, then select Add. 5. Prepare the comment "lung capacity procedure" in the Comment panel.

Note: The following procedure should not be performed rapidly, but at the same speed as a regular tidal breath.

6. After the tidal breathing period, ask the volunteer to inhale as deeply as possible, then exhale all the air they possibly can. At the same time select Add to enter the comment.

7. Afterwards, allow the volunteer to return to normal tidal breathing.

8. Select Stop.

9. Your recording should resemble this. You may want to repeat the lung capacity procedure several times.

10. Complete the table below to predict your volunteer's residual volume (RV). See the height units conversion table, if required.

Your volunteer's predicted values: Residual volume (RV) and lung capacities: Sex (M or F) Height (cm) Age (years) Predicted RV (L) Predicted VC (L) Predicted FRC (L) Predicted TLC (L)

Your volunteer's predicted and measured lung capacities: Predicted Value Experimental Value Vital capacity (VC) (L) Functional residual capacity (FRC) (L) Total lung capacity (TLC) (L)

2. Comment on the differences between the experimental and predicted values for VC, FRC, and TLC in the table above. What could cause these differences, if any?

3. How might lung volumes and capacities be altered in a 74-year-old woman who struggles with breathlessness?

9/16 - Dynamic function tests The forced vital capacity (FVC) procedure involves exhaling air as fast as possible from full inspiration to full expiration. The recording below shows lung volume changing as a healthy person performs this procedure.

1. Place the comments in the appropriate place

10/16 - Dynamic function tests In this activity, you will measure parameters of forced expiration that are used in evaluating pulmonary function. You should use the same volunteer as for the static lung measures activity.

Procedure

- 94 -

1. Re-zero the Spirometer Pod using the Zero Inputs button. Remember, the flow head must be left undisturbed on the bench during the zeroing process.

2. Select Start to record.

3. Ensure the volunteer has the nose clip in place, and breathes normally through the flow head for 1 min.

4. Select Stop and apply the volume correction procedure.

5. Select Start and ask the volunteer to breathe normally for approximately 20 s.

6. Enter "FVC procedure" into the Comment panel.

7. Ask the volunteer to slowly inhale until no more air can be inspired and hold for no more than 1 second. Then exhale as forcefully, as fully, and for as long as possible, until no more air can be expired. During this procedure select Add to enter the comment.

8. Allow the volunteer's breathing to return to normal, then select Stop.

9. Your recording should resemble this.

10. Repeat steps 5–8 twice more, so that you have 3 separate FVC recordings.

11/16 - Dynamic function tests In this analysis of pulmonary function variables, you will follow the steps described below to complete the table. The most important measurement here is of FEV1.

Check your understanding 1. In your own words describe the physiological significance of the FEV1/FVC ratio.

2. Why do you think the forced vital capacity is less than the vital capacity?

3. How would the 74-year-old woman's breathlessness affect her ability to exhale forcefully?

What effect would this have on her test results?

12/16 - Hyperinflated breathing The question here is: "What does it feel like to breathe with hyperinflated lungs?"

Here, the volunteer will breathe with lungs held partially expanded after a large inspiration.

- 96 -

Procedure 1. Re-zero the Spirometer Pod using the Zero Inputs button. Remember, the flow head must be left undisturbed on the bench during the zeroing process.

2. Select Start. Ensure the volunteer has the nose clip in place and breathes normally through the flow head for 1 min.

3. Select Stop and apply the volume correction procedure.

4. Select Start and record normal tidal breathing for about 30 s. Enter "normal tidal breathing" into the Comment panel, then select Add. 5. Ask the volunteer to take a deep breath, breathe out a little, and then breathe in and out on top of this increased lung volume for 30 s (or 1 min, if possible). The volunteer may need to practice this technique 2–3 times before they can manage a 30–60 s recording.

6. Enter "hyperinflated breathing" into the Comment panel and select Add. 7. After the hyperinflated tidal breathing period and at the end of a tidal expiration, ask the volunteer to inhale as deeply as possible and then exhale as fully as possible. Enter the comment "lung capacity procedure" into the Comment panel, then select Add. Afterwards, allow the volunteer to return to normal tidal breathing.

8. Your recording should resemble this.

9. Select Stop.

13/16 - Hyperinflated breathing You will analyze your recordings to investigate how breathing with hyperinflated lungs influences respiratory parameters. View the lung volumes and lung capacities that will be calculated.

Check your understanding 1. Examine the table showing respiratory rate and tidal volume after breathing normally and with hyperinflated lungs. Has respiratory rate or tidal volume changed? How do you account for this?

2. Has there been any change to the lung volumes with hyperinflated breathing?

3. When you compare the rate of breathing with hyperinflated lungs with that in normal breathing, you will notice a significant increase. This will have resulted in an increased expired minute volume. What effect will this have had on blood gases?

4. Patients with an obstructive lung disease often develop hyperinflated lungs, where air becomes "trapped" in the lungs and can't be exhaled. As a consequence, the chest and neck muscles must work harder to assist with breathing. Ask the volunteer to describe how it felt to breathe with hyperinflated lungs.

5. A 74-year-old woman has more air in her lungs than normal, and breathes with an inflated chest. Do you think an inflated chest would make breathing uncomfortable? Would it alter the rate of breathing, or the volume of each breath?

14/16 - Hyperinflated function test Now that the volunteer is accustomed to breathing with hyperinflated lungs, you will perform a pulmonary function test.

Procedure 1. Re-zero the Spirometer Pod by selecting Zero Inputs. Leave the flow head undisturbed on the bench during the zeroing process.

2. Select Start. Ensure the volunteer has the nose clip in place and breathe normally through the flow head for 1 min. Select Stop and apply the volume correction procedure.

3. Select Start. After 20 s of normal breathing, ask the volunteer to start breathing with hyperinflated lungs.

Enter "hyperinflated breathing" into the Comment panel, then select Add. 4. After approximately 20 s, enter "FVC procedure" into the comment panel, then select Add. Immediately ask the volunteer to inhale until they can't inspire any more air, holding for no more than 1 second. Then exhale as forcefully, deeply, and for as long as possible.

- 99 -

5. Afterwards, allow the volunteer's breathing to return to normal then select Stop.

6. Your recording should resemble this.

7. Repeat steps 3–5 twice more, so that you have three separate FVC recordings.

15/16 - Hyperinflated function test In this analysis, you will measure the forced expired volume (FVC) and forced expired volume in 1 second (FEV1) from your data with hyperinflated lungs.

Analysis Forced vital capacity 1.

In the Volume channel, determine which of the 3 recordings shows the greatest or "maximal" FVC. 2.

In the Volume channel, place the point selector at the end of the plateau, directly before the steep decrease in volume.

3.

Place the Marker at the point of maximal expiration (trough).

Lab Activities A. The Effect of Various Factors on the Rate of an Enzyme Reaction All four experiments will use the enzyme catalase, which is found in potatoes. Catalase acts on the substrate, H2O2 (hydrogen peroxide), to produce H2O and O2. The O2 is released as bubbles. Therefore, the more bubbles you see, the greater the reaction.

The effect of temperature on the rate of enzyme reactions a. Prepare three water baths i. Fill three 500 ml beakers with approximately 300 mls of water. ii. To the first beaker add ice; this will be the 0oC bath. iii. To the second beaker do nothing; this will be the 25oC (room temperature) bath. iv. Place the third beaker on a hot plate set on high; when the water boils, this will be your 100oC bath.

While you are waiting for the water baths to reach equilibrium temperature, you can continue to the next step. b. Prepare the test tubes. i. Using a wax pencil, label three test tubes (C1, C2, C3). ii. To each tube, add 1 ml of catalase using a serological pipet. You may use the same pipet repeatedly, but only for catalase. iii. Place tube C1 in the 100oC bath. iv. Place tube C2 in the 25oC bath. v. Place tube C3 in the 0oC bath. vi. Using a wax pencil, label three additional test tubes (P1, P2, P3). vii. To each tube, add 1 ml of H2O2 using a serological pipet. You may use the same pipet repeatedly, but only for H2O2. viii.

Place tubes P1 and P2 in the 25oC bath. ix. Place tube P3 in the 0oC bath. x. Wait at least 15 minutes for the test tubes to equilibrate with the water baths. xi. Remove tube C1 from the 100oC bath (use a tube holder—don’t burn yourself!) and place it in the 25oC water bath alongside. Wait ~5 minutes for tube 1 to cool to 25oC. - 120 -

Return tubes C1 and C2 to the 25oC bath; return tube C3 to the 0oC bath. Observe each tube for bubbling and record your observations in the table above.

Wash your test tubes to use for the next experiment, but SAVE THE CATALASE! The effect of pH on the rate of enzyme reactions a. Prepare the test tubes. i. Using a wax pencil, label 5 test tubes (1, 2, 3, 4, 5). ii. To each tube, add 1 ml of catalase using a serological pipet. You may use the same pipet repeatedly, but only for catalase. iii. Next you will add various buffered solutions. Use a serological pipet to transfer the solution to the appropriate test tube, but make sure to RINSE YOUR PIPET BETWEEN EACH SOLUTIONS. You might want to keep a small beaker of distilled water handy for this purpose. iv. To Tube 1, add 1 ml of pH 3 buffer solution. v. To Tube 2, add 1 ml of pH 5 buffer solution. vi. To Tube 3, add 1 ml of pH 7 buffer solution. vii. To Tube 4, add 1 ml of pH 9 buffer solution. viii.

C. Starch digestion Salivary amylase is produced by the parotid, the submandibular, and the sublingual salivary glands, which empty their secretions by way of ducts into the mouth. Amylase acts on starch and glycogen, hydrolyzing them to maltose.

1. Identify substrate(s), enzyme(s), and product(s) - 124 -

Starch: Maltose: Amylase: 2. Test your saliva for amylase i. Massage your parotid gland for about one minute, or mimic rinsing your mouth to obtain saliva. ii. Place an unsalted saltine on your tongue, without chewing, and close your mouth until you have a sugary taste. The amylase in your saliva has changed the starch in the crackers to smaller sugar molecules. iii. Record the time it took to notice the sugary taste, and compare with the members of your group Are there any differences? Why?

3. Color reactions in enzyme assays: Iodine Reaction We will detect starch digestion (hydrolysis) using a dye - potassium iodine (IKI) -that colors starch molecules, but not maltose, the disaccharide digestion product.

Meiosis.

At which stage of meiosis are homologous pairs lined up on the equator of the cell? ____________ At which stage of meiosis are sister chromatids separated? ____________ At which stage of meiosis does the cell first become haploid? ____________

4. Draw the stages of the meiosis below. Label each stage with its defining events (nuclear membrane dissolves, chromosomes line up at the equator, etc).

- 136 -

5. Meiosis begins with a (haploid/diploid) cell, meaning that it has pairs of (heterozygous / homogenous / homologous) chromosomes (pairs of chromosomes that have alleles of the same genes). The first meiotic division results in the chromosome pairs being separated which produces (haploid/diploid) cells, meaning that there are no chromosome pairs. In the second division, the cell separates each chromosome into two identical copies, called (chromosomes / chromatids / centromeres).

6. In the following exercise, you’ll be demonstrating meiosis using pipe cleaners. To do this, you’ll need eight pipe cleaners in two different colors. In each color, two should be short and two should be long. a) Take two long chromosomes of the same color and twist them together at the middle. This represents a duplicated chromosome and each pipe cleaner represents a sister chromatid. The chromatids are joined at the centromere. Do the same with the other pipe cleaners. b) Once all of the pipe cleaners are doubled, you’re ready to start meiosis. The cell is in Prophase I. c) Arrange the homologous chromosomes (same-sized chromosomes) in pairs, then line them up in a double row along the mid-line of the “cell” (Metaphase I). d) Next, pull the homologous pairs apart. Don’t un-twist the pipe cleaners! During this phase, each chromosome begins to move to an opposite end of the cell (Anaphase I). e) Once the two sets of chromosomes are far enough apart, the cell membrane can begin to divide. Move the two sets of chromosomes completely apart (Telophase I and Cytokinesis). f) The result: you have two new cells; each with half the number of chromosomes that were in the original cell (from diploid to haploid). Each of these cells is now in Prophase II. g) Now you are ready to perform the second meiotic division. Line up the two chromosomes in each of the daughter cells along the midline of the cell. (Metaphase II). h) Drag the chromatids away from each other (Anaphase II). i) Separate the chromatids completely (Telophase II and Cytokinesis). j) You should now have one small and one large chromosome in each of the daughter cells. You may find that the colors are the same or you may find that the colors are different. This shows how we get random distribution of chromosomes in gamete production. k) Save your gametes for Exercise 2 in Mitosis.

B. Mitosis 1. Draw the stages of mitosis here. Label each stage with its defining events (nuclear membrane dissolves, chromosomes line up at the equator, etc).

2. Metaphase in mitosis is most similar to what phase of meiosis?

3. In the following exercise, you’ll be demonstrating fertilization and mitosis using pipe cleaners. To do this, you’ll need two of the gametes that you produced in Exercise 6 above. You can also trade one of your gametes with another group so that you have different colors for each gamete.

- 137 -

a) Take two of the gametes from meiosis. One gamete will represent the oocyte, and the other gamete will represent the sperm. Put the chromosomes from each gamete together in one “cell.” This process represents fertilization and the resulting cell is called a zygote. b) Arrange the chromosomes into homologous pairs (same-sized). Why can’t the cell start mitosis yet? c) Find pipe cleaners of the same size and color and twist them together at the middle with the chromosomes that you already have in the zygote. This represents a duplicated chromosome and each pipe cleaner represents a sister chromatid. The chromatids are joined at the centromere. Do the same with the other pipe cleaners. d) Once all of the pipe cleaners are doubled, you’re ready to start mitosis (Prophase). e) Line up the chromosomes in a row along the mid-line of the “cell” (Metaphase). f) Drag the chromatids away from each other (Anaphase). g) Separate the chromatids completely (Telophase and Cytokinesis). h) You should now have two daughter cells—each with two long chromosomes and two short chromosomes. Each of these cells will continue to replicate its DNA and divide by mitosis (development). But we’ll talk about that next week.

2. Know your own allergies and be aware of the potential allergens (e.g. penicillin, pollen, latex) that might be present in the laboratory. Take the necessary precautions to prevent allergic reactions.

3. Know where the shower, eyewash bath, and fire extinguisher are and how and when to use them.

4. Do not put backpacks, bags, and other personal items on the lab bench. Keep them out of the way under the bench.

5. Follow all protocols (instructions for experimental procedures) carefully. Varying the order could be dangerous.

6. Approach all chemicals with caution. Do not taste or inhale (smell) chemicals. Avoid getting chemicals on your skin. We may use strong acids and bases that can cause chemical burns. We may use chemicals that have been linked to causing cancer (carcinogens).

7. Wash your hands before and after each laboratory session. Good hygiene is important in limiting the spread of disease. Hand-washing will also get rid of any chemical residues you might have inadvertently been exposed to.

8. No food or drink in the laboratory, including water. If you are thirsty or hungry, leave the classroom.

9. Smoking is prohibited in all public buildings in New York City, including this one.

10. Report accidents and breakages or any equipment that is malfunctioning to your professor. Do not attempt to clean up any spills or breakages yourself. Tell your professor.

11. Long hair and flowing clothing can be dangerous in the laboratory because they can get caught. Opentoed shoes or sandals are not to be worn in the lab because chemicals might spill directly on your skin. You may bring an old shirt to class to wear over you clothing.

12. Do not wear contact lenses in the lab. Lenses may absorb fumes and cause permanent damage.

13. Never remove chemicals, equipment, or parts of models from the laboratory. Anyone caught doing so is subject to disciplinary action.

14. Leave the lab in the same or better condition than when you entered. Put all microscopes back properly.

Clean lab benches. Return all materials to the cart. Wash any glassware, slides, trays that you have used.

Dispose of specimens in appropriate containers.
