Answer

The antidiuretic hormone is responsible for maintaining blood pressure and water reabsorption rates. ADH is synthesized by neurons in the hypothalamus and secreted from nerve endings in the posterior pituitary gland. ADH is released by hypothalamic osmoreceptor signaling and inhibited by stretch receptors located in the arteries. This causes the renal excretion of solutes to decrease blood osmolarity.
