The question for one of his practice exams was "Maintaining Na/K balance in the body is the function of the a) kidney b)pancreas c) small intestine d) adrenal glands.

I put d) adrenal glands because he taught us that aldosterone, which is found in adrenal glands, regulates the Na/K balance but the answer was a) kidney. Can someone help explain why kidney is a better answer? thanks!

You are right but also Aldosterone causes more Na channels and Na/K pumps to be inserted into the membrane of the distal tubule of the nephron to allow more Na reabsorption.

It also predominates in the kidneys meaning you find more pumps there.

Hope it sort of helps
