Aldosterone is a mineralocorticoid hormone, which is produced by the adrenal cortex in response to low blood pressure or low blood volume. It acts on the kidney cells to stimulate the reabsorption of sodium ions and water from the filtrate, which increases blood volume and blood pressure. Progestins, catecholamines, glucocorticoids, and adrenocorticotropic hormone do not have this function.
