In brief: Quite efficiently

To simplify a very complex symbiotic relationship, the respiratory system brings oxygen to the alveolar surfaces of the lung where it passes into the red blood cells of the circulatory system to be taken to the rest of the body.
Simultaneously red cells give up carbon dioxide brought to the lungs that is exhaled by the respiratory system. This exchange continues 24/7. Wish my car worked as well!
