Hormone regulates the transfer of sodium from the nephron to the blood:
Correct answer: C. Aldosterone
- A. Parathormone
- B. Anti-diuretic
- C. Aldosterone
- D. Vasopressin
Explanation
Aldosterone is a hormone produced by the adrenal glands that primarily regulates the balance of sodium and potassium ions in the blood by acting on the kidneys. It promotes the reabsorption of sodium ions and the excretion of potassium ions, thus indirectly affecting blood sodium levels.

About Homeostasis
Homeostasis maintains a stable internal environment through the kidney and urinary system, thermoregulation and excretion. The kidney topics include filtration, selective reabsorption, urine formation and water balance, while thermoregulation involves sweating, vasodilation, vasoconstriction and hormonal control; excretion is different from egestion, which removes undigested food.
