Aldosterone (redirected from Aldosteron)

aldosterone /al·dos·ter·one/ (al-dos´ter-on) the major mineralocorticoid hormone secreted by the adrenal cortex. It promotes the retention of sodium and bicarbonate, the excretion of potassium and hydrogen ions, and the secondary retention of water. Large excesses can invoke plasma volume expansion, edema, and hypertension.

al·dos·ter·one (l-dst-rn)

n.

A steroid hormone secreted by the adrenal cortex that regulates the salt and water balance in the body.

Aldosterone

A hormone secreted by the adrenal glands that is important for maintaining salt and water balance in the body.

Mentioned in: Congenital Adrenal Hyperplasia

---

aldosterone (al·dsˑ·t·rōn),

n an adrenal hormone that causes elevation of blood pressure through the retention of sodium and the resultant increase in blood plasma volume.

---

aldosterone (aldos´trōn),

n an adrenal corticosteroid hormone that acts primarily to accelerate the exchange of potassium for sodium in the renal tubules and other cells. It is a potent mineralocorticoid but also has some regulatory effect on carbohydrate metabolism.

aldosterone

the main mineralocorticoid hormone secreted by the adrenal cortex, the principal biological activity of which is the regulation of electrolyte and water balance by promoting the retention of sodium (and, therefore, of water) and the excretion of potassium; the retention of water induces an increase in plasma volume and an increase in blood pressure. Its secretion is stimulated by angiotensin II. Deficiency is hypoadrenocorticism (Addison's disease).
