Solution:

Mineralocorticoids hormones are 21-carbon steroids secreted by the cells of zona glomerulosa of adrenal cortex. The principal mineralcorticoid is aldosterone. It is a salt retaining hormone”. It upgrades sodium ion concentration in the ECF by promoting reabsorption of sodium ions from renal tubules and excretion of potassium ions in urine.
