Aldosterone is a hormone that is produced by the adrenal glands, specifically in the outer layer known as the adrenal cortex. Its main function is to regulate the body’s electrolyte balance, with a focus on sodium and potassium levels. This hormone primarily acts on the kidneys, where it increases the reabsorption of sodium ions and the excretion of potassium ions. These actions are crucial in maintaining normal blood pressure, blood volume, and electrolyte concentrations in the body. The release of aldosterone is influenced by various factors, including blood pressure, blood volume, and potassium levels. It is a vital component of the renin-angiotensin-aldosterone system, which is a complex regulatory mechanism for blood pressure and fluid balance.
