NEET PG DENTAL EXAM

Detailed explanation-1: -What is aldosterone? Aldosterone (ALD) is a hormone your adrenal glands release that helps regulate blood pressure by managing the levels of sodium and potassium in your blood.

Detailed explanation-2: -A steroid hormone made by the adrenal cortex (the outer layer of the adrenal gland). It helps control the balance of water and salts in the kidney by keeping sodium in and releasing potassium from the body.

Detailed explanation-3: -The body senses a low mean arterial blood pressure when the ECF is low. Therefore the renin-angiotensin system is activated. This causes an increase in water absorption as well as activation of aldosterone. Aldosterone causes sodium to be absorbed and potassium to be excreted into the lumen by principal cells.

Detailed explanation-4: -Aldosterone regulates the salt and water balance of the body by increasing the retention of sodium and water and the excretion of potassium by the kidneys (and to a lesser extent by the skin and intestines). It also has a limited effect on the metabolism of fats, carbohydrates, and proteins.
