Final answer:
The respiratory system provides for the oxygenation of blood and the elimination of carbon dioxide from the body.
Step-by-step explanation:
The respiratory system provides for the oxygenation of blood and the elimination of carbon dioxide from the body. It is responsible for the exchange of gases between the body and the outside air. The oxygen is drawn into the body and carbon dioxide is released through the respiratory tract. The circulatory system then delivers the oxygen to body cells and picks up carbon dioxide from the cells for removal from the body.
