Aldosterone is a hormone released by the adrenal glands. It is part of the complex mechanism used by the body to regulate blood pressure. Aldosterone increases the reabsorption of sodium and the excretion of potassium in the distal tubules of the kidneys. The reabsorption of sodium is accompanied by the reabsorption of water, which raises blood pressure.
