The function of the circulatory system. To deliver food and oxygen to cells. To carry away waste. To aid in disease prevention. -

The function of the circulatory system. To deliver food and oxygen to cells. To carry away waste. To aid in disease prevention. To deliver chemical messages (hormones).

By delivering food and oxygen to cells and carrying waste products away, the circulatory system maintains a state of homeostasis in your body. Copyright © 2010 Ryan P. Murphy

What happens to the blood when the heart beats? The beating PUSHES blood through the blood vessels.

Function of the Chambers 2 Atria- receive blood that comes to the heart. 2 Ventricles – pump blood out of the heart

Valves Flap of tissue that prevents blood from flowing backward.

What force pushes blood out of heart and into arteries? Contraction of the ventricles
