Teaching Cardiovascular system

Cardiovascular system

The cardiovascular system is made up of the heart, the blood vessels, and the blood. It moves nutrients, gases (like oxygen), and wastes to and from your cells. Every cell in your body depends on your cardiovascular system. If your cells don't receive nutrients, they cannot survive. The main function of the cardiovascular system is to deliver oxygen to each of your cells.
