The exchange of oxygen and carbon dioxide happens in between the alveoli and then through the walls of the capillaries and then into the blood. The oxygen is then picked up by hemoglobin in the red blood cells and sent to all body cells. While this is happening the carbon dioxide is transported back from the body cells and into the blood. It diffuses through the walls of the capillaries and into the walls of the alveoli. Carbon dioxide leaves your body whenever you breathe out.
