1. Circulatory System By: Audrey

2. Each breath you take brings air into your lungs. That air is needed by the trillions of cells in your body. Your heart is essential in delivering that oxygen. It’s beating produces the force to move oxygen rich blood threw the circulatory system.

3. Function Brings oxygen, nutrients, and hormones to cells. Fights infections Regulates body temperatures

4. Structures Heart Arteries Veins

5. Heart

6. Arteries Arteries carry mostly oxygenated blood away from the heart to the tissue and organs in the body

7. Veins The Veins are responsible for the transportation of deoxygenated blood back to the heart.

8. Diseases High blood pressure Heart attack Stroke

9. High Blood Pressure Forces the heart to work harder, which may weaken or damage the heart mussels and blood vessels.

10. Heart Attack Coronary arteries, a set of arteries that bring oxygen and nutrients to the heart. If one of these arteries becomes blocked, part of the heart may begin to die due to lack of oxygen.

11. Stroke Blood clots break free and gets stuck in one of the blood vessels leading to the brain.

12. Blood Types If two different blood types are mixed together, the blood cells may begin to clump together in the blood vessels, causing a potentially fatal situation. Therefore, it is important that blood types be matched before blood transfusions take place. In an emergency, type O blood can be given because it is most likely to be accepted by all blood types.

13. Donating Blood A person with type A blood can donate blood to a person with type A or type AB. A person with type B blood can donate blood to a person with type B or type AB. A person with type AB blood can donate blood to a person with type AB only. A person with type O blood can donate to anyone.

14. Receiving Blood A person with type A blood can receive blood from a person with type A or type O. A person with type B blood can receive blood from a person with type B or type O. A person with type AB blood can receive blood from anyone. A person with type O blood can receive blood from a person with type O.
