What are the functions of the circulatory system? |
The primary function of the circulatory system is to transport oxygen and nutrients to all the cells of an organism. The circulatory system also transports wastes from the cells to waste-disposal organs such as the lungs for carbon dioxide and the kidneys for other metabolic wastes. In addition, the circulatory system plays a vital role in maintaining homeostasis—in other words, to keep your entire system balanced.
