WebNatriuretic hormones are peptides that stimulate the kidneys to excrete sodium—an effect opposite that of aldosterone. Natriuretic hormones act by inhibiting aldosterone release and therefore inhibiting Na + recovery in the collecting ducts. If Na + remains in the forming urine, its osmotic force will cause a concurrent loss of water. camo waterfowlWebThe atrial natriuretic peptide (ANP) lowers blood pressure by acting as a vasodilator.
