The hormone produced by the adrenal cortex that is crucial for regulating salt and water balance is a mineralocorticoid, specifically aldosterone. Mineralocorticoids help control the balance of electrolytes in the body, particularly sodium and potassium. They significantly influence the kidneys' functioning by promoting the reabsorption of sodium into the bloodstream and the excretion of potassium. This process not only helps maintain electrolyte balance but also plays a vital role in regulating blood pressure and fluid balance in the body.

Cortisol, although produced by the adrenal cortex, primarily affects carbohydrate metabolism and stress response, rather than directly regulating salt and water. Glucagon, on the other hand, is produced by the pancreas and raises blood glucose levels, which is unrelated to salt and water balance. Epinephrine, also known as adrenaline, is produced by the adrenal medulla and is involved mainly in the body's fight-or-flight response, affecting heart rate and energy mobilization but not specifically in the regulation of water and electrolyte balance.
