Oxygen diffuses from the blood to the body's tissues, and carbon dioxide diffuses from the tissues to the blood. Oxygen diffuses from alveoli in the lungs into capillaries. Breathing moves air in and out of the lungs. Carbon dioxide leaves the body when exhaled. Oxygen enters red blood cells, where it binds to the protein hemoglobin.
