How Does the Kidney Regulate Body pH

The kidneys have two main ways to maintain acid-base balance – their cells reabsorb bicarbonate HCO3− from the urine back to the blood and they secrete hydrogen H+ ions into the urine. By adjusting the amounts reabsorbed and secreted, they balance the bloodstream’s pH.

Do your kidneys change your body's pH?

The kidneys can regulate reabsorption of carbonic acid in the tubule, increasing or reducing acid secretion. So, urine that is more acidic than normal may mean the body is ridding itself of excess dietary acid and thus making blood pH more alkaline. Ammonia is another way the kidney can regulate pH balance.

How do the kidneys help regulate pH quizlet?

– The kidneys excrete a variable amount of hydrogen ions (H+) into the urine and conserve bicarbonate ions (HCO3-), which are an important buffer of H+ in the blood. Both of these activities help regulate blood pH.
