The lungs and kidneys are the principal organs that regulate the pH of the carbonic acid-bicarbonate buffer system in the blood. The lungs regulate the partial pressure of carbon dioxide (CO2), which determines the amount of carbonic acid (H2CO3) in the blood. The kidneys regulate the amount of bicarbonate (HCO3-) ions in the blood. Together, the lungs and kidneys maintain a balance between the production and elimination of carbonic acid and bicarbonate ions to keep the blood pH within a normal range.
