Working closely with the cardiovascular system, blood passes through the tiny capillaries in the alveolar sacs. The change in a pressure gradient between the blood and alveoli allows oxygen to diffuse across the thin walls of the alveoli into the and to diffuse outward from the red blood cells into the lungs. To get the gases to and from the alveoli, , a mechanical process that involves the use of the rib cage and the , must occur. Control over the rate of breathing is done by in the blood vessels that relay information on the and acidity levels of the blood to the brain. When the body generates high amounts of carbon dioxide, the pH of the blood and becomes too . The body will the breathing rate to reduce the amount of carbon dioxide in the blood and move the pH toward its . If the blood becomes too basic, this will trigger a physiological change to the breathing of the body and to the amount of carbon dioxide and lower the pH.

In the body, the enzyme carbonic anhydrase speeds up the formation or breakdown of carbonic acid to maintain blood pH and levels of CO₂. When carbon dioxide enters the blood, some of it combines with hemoglobin to form carbaminohemoglobin, but most of it becomes bicarbonate ions that diffuse into the blood plasma.
