1. Do now! Can you continue the questions you started yesterday (on pages 16 and 17)

2. Today’s lesson Know how blood is transported around the body. Know what system the heart and blood vessels belong to. Know why the heart has two valves Know what the different blood vessels in the body are.

3. Last lesson - Aerobic Respiration Occurs in the cytoplasm of cells Glucose + oxygencarbon dioxide + water (+ energy) Reactantsproducts The same reaction as burning, but there’s no flame because the reaction is carefully controlled (slower)

4. Blood Oxygen and digested food travel around the body in blood. The blood travels around the body in tubes called blood vessels.

5. Blood vessels There are three main types of blood vessels

6. Blood vessels capillaries – The smallest vessels with thin walls that allow small molecules like oxygen and glucose to pass through them

7. Blood vessels arteries – Thick walled tube which carry blood from the heart to the body

8. Blood vessels veins – Thinner walled tubes which carry blood back to the heart.

9. The heart

10. (to the lungs) (from the lungs) (to the rest of the body) (from the rest of the body) BBC - GCSE Bitesize - Physical Education | Anatomy and physiology | The passage of blood through the heart

11. The circulatory system The circulatory system is made up of the heart and all the blood vessels

12. The circulatory system Blood goes from the heart to the lungs (to pick up oxygen), it returns to the heart where it is then pumped around the rest of the body. It returns to the heart and the process starts again.

13. Sheets Can you complete the two sheets “The circulatory system” and “Blood and circulation”

14. How fit are you? In pairs one of you is going to run on the spot for 2 minutes You will then measure your heart rate over a period of 10 minutes

15. Fit? Time (mins) YOU # beats in 20 secs YOU Heart rate (per min) PARTNER # beats in 20 secs PARTNER Heart rate (per min) 0 1 2 3 4 5 6 7 8 9 10

16. How to measure pulse Check your pulse at your wrist. Use two fingers - your index and middle. Count how many beats in 20 seconds and multiply that number by three to get your heart rate.

17. Graph Conclusion: Two sentences describing what you have discovered

18. Can you gather around Mr Porter?

19. Lung capacity Measure your lung capacity three times and calculate the average result Design a table of results to find the lung capacity of ten people in the class Find the average lung capacity in the class Plot an appropriate graph
