Although aldosterone retains Sodium and water, it induces excretion of Potassium. Potassium can be induced by angiotensin II. Antidiuretic Hormone (ADH) ADH is a polypeptide, which is secreted by the hypothalamus, and it is stored in the posterior pituitary gland. ADH is released when water level is low in the blood stream. ADH regulates the body water level by concentrating urine and thereby reducing urine volume.
