Also known as: Cardiovascular system Description: The circulatory system uses blood to deliver oxygen and nutrients and
remove carbon dioxide and wastes from the organs and tissues of the body.
In addition to the blood, the circulatory system consists of the heart,
which pumps the blood throughout the system, and blood vessels (arteries,
veins, and capillaries) that carry the blood. Oxygen and carbon dioxide are
exchanged when blood passes through the lungs, and wastes are removed when
blood passes through the kidneys. |
