oxygen
Inhalation
The cardiovascular system transports the oxygen brought in by the respiratory system to other areas of the body.
The respiratory system provides oxygen so the body can "burn" (oxidize) the food that is brought into the body through the digestive system. The circulatory system brings nourishment to all cells of the body. The circulatory system exchanges critical gases with the respiratory system; unneeded carbon dioxide is exchanged for much needed oxygen.
