The cardiovascular system performs numerous functions. The heart pumps blood throughout the entire body. Part of the cardiovascular system's function includes pumping blood to the lungs for oxygenation. Another part of the system includes the arterioles and capillaries distributing blood to the rest of the body. The distribution of oxygen through the body also enables the nervous system to function normally because the brain needs oxygen provided by the circulation of oxygenated blood. The blood traveling through the body also carries nutrients to different parts of the body where they can be used to make energy.
