Aldosterone tells the kidney to hold on to sodium
This adrenal hormone increases sodium reabsorption while pushing potassium out Aldosterone is made in the outer layer of the adrenal cortex and acts on the far end of the kidney tubule. It increases the number of sodium channels and pumps in those cells, so more sodium and water stay in the body. Potassium leaves in exchange, which is why the hormone affects both salt balance and blood volume. It sits in Mondo's human body collection, one of 200 facts that each trace back to the reference below.
