It acts primarily on the kidneys, where it promotes the reabsorption of sodium and the excretion of potassium, thereby increasing water retention in the body and contributing to maintaining blood pressure. It is responsible for producing a hormone called aldosterone, which is a mineralocorticoid hormone.Īldosterone plays a crucial role in regulating water and electrolyte balance in the body, particularly in sodium and potassium homeostasis.
