oxygen and carbon dioxide
Inhalation
The respiratory system removes gaseous waste such as carbon dioxide from the body. This waste is eliminated when we exhale.
The cardiovascular system transports the oxygen brought in by the respiratory system to other areas of the body.
Carbon dioxide is a waste material removed by the respiratory system through exhalation. It is a byproduct of cellular respiration and needs to be eliminated to maintain the body's proper pH balance.
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.
