Angiotensin II and aldosterone are the most important hormone regulators of electrolyte reabsorption and secretion. Angiotensin II acts on the proximal tubule to increase sodium and water reabsorption, while aldosterone acts on the late distal tubules and collecting ducts to increase sodium reabsorption and potassium secretion. ADH also plays a role in regulating electrolyte balance but primarily affects water reabsorption rather than sodium and potassium reabsorption. Atrial natriuretic peptide, on the other hand, promotes sodium and water excretion to reduce blood pressure. Epinephrine does not directly regulate electrolyte balance but can affect sodium and water reabsorption indirectly by promoting vasoconstriction and increasing blood pressure.
