How would the kidneys respond to a decrease in blood pH caused by a high protein diet? A) Increased HCO₃- secretion and H+ reabsorption B) Increased production of renin and ADH C) Increased H+ secretion and HCO₃- reabsorption D) Increased secretion of both H+ and HCO₃- E) Increased reabsorption of both H+ and HCO₃-

Question

To counteract a decrease in blood pH (acidosis), the kidneys increase the secretion of hydrogen ions (H+) into the urine and reabsorb bicarbonate ions (HCO3-) back into the blood. This process helps to buffer the blood pH by removing excess H+ and conserving HCO3-, which acts as a base.
