Aldosterone from the adrenal cortex causes sodium ions to be conserved and potassium ions to be excreted.
Aldosterone is produced by the adrenal glands and is responsible for regulating the metabolism of electrolytes, it acts in the conservation of sodium, both by secreting potassium and increasing blood pressure.
- It belongs to the group of mineralocorticoids, aldosterone increases blood pressure and contributes to potassium secretion and sodium storage.
- The secretion of aldosterone acting on the kidney causes the reabsorption of Na +, which passes into the plasma where it proceeds as a water retention factor, thus contributing to the restoration and / or conservation of plasma volume.
Therefore, we can conclude that aldosterone induces functional modifications in the cell that affect Na reabsorption and K excretion, especially in the renal tubules.
