Circulatory System. This system is made up of the heart, blood, blood vessels, and lymphatics. It is the bodyâs delivery system, concerned with circulating blood to deliver oxygen and nutrients to every part of the body.
All cells in the body need to have oxygen and nutrients, and they need their wastes removed. These are the main roles of the circulatory system. The heart, blood and blood vessels work together to service the cells of the body. Using the network of arteries, veins and capillaries, blood carries carbon dioxide to the lungs (for exhalation) and picks up oxygen. From the small intestine, the blood gathers food nutrients and delivers them to every cell.
