Gas exchange primarily occurs in the alveoli of the lungs. The alveoli are tiny air sacs where oxygen from the inhaled air diffuses into the bloodstream and carbon dioxide from the blood diffuses into the alveoli to be exhaled. This exchange of gases is facilitated by the thin walls of the alveoli and the surrounding capillaries.
