Refresh How many body systems does a human being have?

What are organs?

Some organs in the human body work together to perform a specific function. These groups of organs are called systems. Each system contains two or more organs that work together to achieve a common objective, such obtaining nutrients.

The major systems in the human body are the respiratory system, the digestive system, the circulatory system, the excretory system, the reproductive system, the nervous system and the locomotor system.

1 Correct the sentences in your notebook.

a) Systems are tissues that work together.

b) Each system is made up of only one organ.

3 Label the photos with the correct system and the correct vital function in your notebook.

1 Look at the picture of Pip’s aunt. She is a doctor. She works at a hospital and she is very worried that they cannot treat some patients because there is not enough blood in the blood bank.

2 What do hospitals need blood for? Write the answers in your notebook.

3 In pairs, do some research. Can a person receive blood from everybody? Find information about the different blood types. Which ones are the least common?

4 Ask your parents what your blood type is. Then carry out a survey in your class to find out how many people have each blood type. Organise the data in your notebook in the form of a pie chart.

5 Blood comes from donors, people who choose to give some of their blood so that other people can be treated and cured. The number of blood donations is very low. Why do you think people do not give blood more often?

6 In small groups, try to think of ways to motivate and persuade people to give blood. Explain why it is so important. Share your ideas with the class.

7 Your class is going to organise an event to make people aware of the importance of donating blood. In pairs, think of an activity that you could do on that day. It has to be persuasive, informative and fun!

7 Make a list of all the activities mentioned in class and organise a program. Design a leaflet to hand out to promote the event that includes the activities and the times. Remember to include the reason why you are organising this event: becoming a blood donor is important.
