How does the carbonic acid-bicarbonate buffer system of blood

Jul 02, 2009 · Answers. The enzyme that combines water and CO2 to make carbonic acid is called carbonic anhydrase. This occurs mainly in the capillaries of the circulation system. The bicarbonate (HCO3-) ions then are transported through the circulation system until they reach the lungs, when they combine with hydrogen ions to form CO2 and water.
