In the respiratory membrane, the compensation activity that takes is the elimination of CO₂ to adjust bicarbonate to carbonic acid it to its normal ratio of 20 : 1 by increase respiratory rate.
In the respiratory membrane, CO2 is eliminated. The regulation of the pH in the kidney involves the secretion of hydrogen ions into the tubular fluid, the reaction of hydrogen ion and bicarbonate gives carbonic acid which is then decomposed to form carbondioxide and water.
