Question

Quizplus · Accepted Answer

The kidneys play a crucial role in maintaining acid-base balance by excreting fixed acids that cannot be eliminated by the lungs, generating new bicarbonate ions to buffer acids when blood pH falls, and regulating the concentration of bicarbonate ions in the blood. They do not secrete bicarbonate ions when blood pH rises; instead, they adjust bicarbonate reabsorption and acid secretion to maintain balance.
