ANTIDIURETIC HORMONE • ADH is a hormone that controls the reabsorption of water molecules in the collecting tubules of the kidneys by affecting the tissue's permeability. • It also increases arterial blood pressure. • It is synthesized in the hypothalamus and stored in the posterior pituitary.
ALDOSTERONE • Aldosterone is produced in the adrenal cortex. • When blood volume is low, aldosterone promotes reabsorption of water in the distal tubules of the kidney. • This leads to increased blood volume and pressure.
