The circulatory system, also called the cardiovascular system or the vascular system, is an organ system that permits blood to circulate and transport nutrients (such as amino acids and electrolytes), oxygen, carbon dioxide, hormones, and blood cells to and from the cells in the body to provide nourishment and help in fighting diseases, stabilize temperature and pH, and maintain homeostasis.
Blood is the final component of the circulatory system. Blood is made up of a liquid called plasma and three particles called red cells, white cells, and platelets. An average adult has about 5 quarts of blood in their body. The circulatory system works together with other body systems. It works with the respiratory system to deliver oxygen. When you take in a breath of air with your lungs, the oxygen passes into your blood stream.
