Explain the Functions of Mineralocorticoids

Aldosterone is the name given to the main physiological mineralocorticoid. As you go through the functions listed below, you will realize that aldosterone is associated with the maintenance of electrolyte balance in the body. Let us get to know about the functions of aldosterone.

  • Aldosterone increases sodium reabsorption in the renal tubules, especially from the ascending limb of loop of Henle and Distal Convoluted Tubule (DCT) and the collecting tubule. When the amount of sodium reabsorbed is increased, the amount of potassium excreted is increased. Thus aldosterone helps in the uptake and retention of sodium in all cells and the extrusion of potassium from them.
  • Aldosterone tends to decrease the acidity of body fluids. Like potassium, the hydrogen ions are secreted into the tubules. Hydrogen ions originate from bicarbonic acid. When hydrogen ions are secreted, bicarbonate ions are left in the extra cellular fluid, resulting in alkalosis.
  • Aldosterone causes an enhanced absorption of chloride ions. Sodium, chloride and bicarbonate ions are accumulated in the extra cellular fluid. As a result, there is an increased water re-absorption.

 

Functions of aldosterone are, thus, associated with the maintenance of electrolyte balance in the body.
