PATHOLOGY

Detailed explanation-1: -Aldosterone is the hormone that stimulates the body to retain sodium and water. This hormone is secreted by the adrenal cortex which maintains the balance of sodium and potassium in the human body. It is responsible for the reabsorption of sodium ions and water from the kidney.

Detailed explanation-2: -Aldosterone signals certain organs, like your kidneys and colon, to increase the amount of sodium they send into your bloodstream or the amount of potassium released in your urine (pee). Aldosterone’s effect on sodium increase causes your body to retain water in your blood, which increases blood volume.

Detailed explanation-3: -Aldosterone release causes sodium and water retention, which causes increased blood volume, and a subsequent increase in blood pressure, which is sensed by the baroreceptors. To maintain normal homeostasis these receptors also detect low blood pressure or low blood volume, causing aldosterone to be released.
