Explanation:
Detailed explanation-1: -The posterior lobe of the pituitary gland stores and releases (secretes) only two hormones: Antidiuretic hormone (ADH, or vasopressin): ADH helps regulate the water balance in your body by controlling the amount of water your kidneys reabsorb while they’re filtering wastes out of your blood.
Detailed explanation-2: -The posterior lobe produces two hormones, vasopressin and oxytocin. These hormones are released when the hypothalamus sends messages to the pituitary gland through nerve cells. Vasopressin is also known as antidiuretic hormone (ADH).
Detailed explanation-3: -ADH then acts primarily in the kidneys to increase water reabsorption, thus returning the osmolarity to baseline.
