Cardiovascular System
The cardiovascular system is a closed system of the heart and blood vessels. The heart pumps the blood while the blood vessels allow blood to circulate to all parts of the body.
The cardiovascular system functions to deliver oxygen and nutrients to cells and tissues. It also removes carbon dioxide and other waste products from cells and tissues.
