Gas exchange occurs in the alveoli of the lungs, where oxygen from the inhaled air passes into the bloodstream, and carbon dioxide from the blood is expelled into the alveoli to be exhaled. The oxygen is then transported by red blood cells to tissues and organs throughout the body, where it is used for cellular respiration to produce energy. Carbon dioxide, a byproduct of this process, is carried back to the lungs for removal.
