What compensates for a metabolic alkalosis?

Question

Quizplus · Accepted Answer

Hypoventilation compensates for a metabolic alkalosis by retaining carbon dioxide (CO2) in the bloodstream, which increases the concentration of hydrogen ions (H+) through the reaction: CO2 + H2O → H2CO3 → H+ + HCO3-. This helps to decrease the pH and correct the alkalemia. Hyperventilation would exacerbate the alkalosis by decreasing the CO2 concentration and increasing the pH. Renal excretion of bicarbonate (HCO3-) or retention of hydrogen ions (H+) would also exacerbate the alkalosis.
