1. Use your own paper Name one organ in the circulatory system. TURN IN YOUR PROJECT!!!!!

2. Life Science Mr. Petriccione

3. The circulatory system carries blood to every part of the body

4. It works with the respiratory system It uses a network of transport tubes, acting like a set of highways and roads.

5. Arteries-carry oxygen rich blood to the cells Veins-carry carbon dioxide blood away from cells Capillaries-exchanges oxygen and carbon dioxide between cells

6. The Heart

7. The heart moves blood through four chambers

8. What do arteries do?

9. It enters the right atrium from the vena cava

10. It goes through a valve to the right ventricle The valve prevents blood from flowing back

11. It goes to the pulmonary artery that moves blood to the lungs

12. It picks up oxygen at the lungs

13. It returns to the heart through the pulmonary vein, entering the left atrium

14. From the left atrium, it passes through another valve to the left ventricle The valve prevents blood from flowing back

15. From the left ventricle, it flows to the aorta and out to the body

16. From the Aorta, it moves to arteries and then to capillaries

17. From the capillaries, it drops off oxygen and nutrients at the cells

18. After dropping off the oxygen, the blood moves from the capillaries to the veins to the vena cava

19. What are the four parts (chambers) of the heart?

20. The muscle cells of the heart shorten, causing the muscle fibers to shorten, and the heart muscle to contract

21. Use your own paper What does a valve do?

22. Blood transports oxygen and nutrients to other parts of the body

23. Liquid part of blood

24. Carry oxygen, using hemoglobin

25. Binds oxygen to the red blood cells, using iron

26. Help the body fight infection

27. Help in clotting, to stop bleeding

28. Who has ever heard of it? What is it?

29. Shape of Blood Cells is sickle-shaped What is a sickle?

33. Shortened life expectancy Blood clots are more common because the sickle shape lumps together Oddly, people with sickle cell anemia are immune from malaria It is a genetic disorder
