Let's remember previous learned concepts...

What are the levels of organization in living organisms?

6
New knowledge beginning... • The total of all chemical reactions carried out by an organism, is called metabolism. • The chemical reactions that use energy to build METABOLISM molecules are called anabolic reactions, or Anabolism. • Reactions that harvest energy when chemical bonds are broken down are called catabolic reactions, or Catabolism.

Circulatory System
8
The Circulatory System • The Cardiovascular system is like a network of highways that transports chemicals to and from all of the cells in the body. • Nearly every material needed by cells travels through this system. What are the parts and functions of the Circulatory System? • The heart, blood vessels and blood make up the cardiovascular system. • The cardiovascular system carries nutrients, oxygen, hormones, and wastes through the body and distributes heat to maintain homeostasis.

The Circulatory System
11
12
• The Circulatory System transports oxygen, nutrients, and wastes through the body in the blood.
• The liquid part of the blood called Plasma (mostly water) contains dissolved nutrients and waste products (CO2).
• The solid part of the blood includes: red blood cells white blood cells
• Blood also contains platelets, tiny pieces of blood cells inside membranes. Platelets cause blood cells to clot when a blood vessel is cut.
13
14
15
Blood Cells • Red blood cells absorb oxygen from air into the lungs and transport it into every cell in the body. They also transport carbon dioxide from the cells to the lungs to be exhaled. • White blood cells help the body fight infection. They attack and destroy viruses and bacteria that enter the body.

Blood Types
Animation
• A blood type is determined by the presence or absence of markers on the surface of red blood cells. • The blood types belong to the ABO system, which contains: A, B, AB, and O. • The letters A and B refer to carbohydrates on the surface of RBCs that act as antigens. • Antigens are substances that can cause the immune system to react.
21
The Heart • Is an organ made of muscle tissue, pumps blood through blood vessels. • The heart has four chambers, (right and left atrium, and right and left ventricle). • Oxygen‐rich blood from the lungs enters the left atrium, it moves to the left ventricle, from which it is pumped to the body. • Oxygen‐poor blood from the body enters the right atrium, it moves to the right ventricle , from which it is pumped to the lungs.
22
23
24
Blood Vessels • Blood leaves the heart through blood vessels (tubes) called arteries. • Arteries lead to capillaries, which are blood vessels so small that blood cells have to move through them in single file. • As there are capillaries throughout the body, nutrients and oxygen can reach every cell, as well as waste products can be picked up by the plasma portion of blood. • Capillaries lead to larger vessels, called veins, which return blood to the lungs.

27
Respiratory System
28
Respiratory System • Why does your body need oxygen? • It needs oxygen because it participates in a life process that happens in the cell to obtain energy, called cellular respiration. • When you inhale, several liters of air are pulled into your body, the air is filtered by tiny hairs in your nose and warmed by capillaries that line the nasal passages. • Warm, clean air then travels down your trachea or windpipe.
29
30
Breathing In • At the same time, oxygen from inhaled air diffuses through the alveoli and into the red blood cells in the capillaries. • This oxygen‐rich blood then flows from the capillaries into the pulmonary veins and back to the heart (left ventricle). • From the heart, oxygen‐rich blood is pumped to other parts of the body.
31
Breathing Out • In your chest, the trachea branches into two tubes called bronchi. Each tube leads into a lung. • In the lungs, the bronchi divide into smaller and smaller tubes. At the end of the smallest tubes are tiny air sacs called alveoli. • The capillaries surrounding the alveoli get blood from the pulmonary arteries coming from the heart. This blood contains a lot of CO2, a waste produced by cellular respiration. • CO2 diffuses through the alveoli and is exhaled into the air.
