The blood circulatory system, also called the cardiovascular system, consists of the heart and the blood vessels that run throughout the body. It delivers nutrients and oxygen to all cells of the body.
The oxygen we breathe gets mixed into the blood in the lungs, and the heart pumps this blood to all parts of the body. Each heartbeat is a contraction of the heart as it pumps blood around the body.
