The hormone which increases the reabsorption of calcium ions in nephron is
Correct answer: B. Parathormone
- A. Aldosterone
- B. Parathormone
- C. Anti-diuretic hormone
- D. Vasopressin
Explanation
Parathormone, or parathyroid hormone, is responsible for increasing the reabsorption of calcium ions in the nephron, particularly in the distal convoluted tubule, to maintain calcium balance in the body. This hormone is crucial for regulating calcium levels in the blood. Aldosterone, option A, is involved in sodium and potassium balance, not calcium. Option C, Anti-diuretic hormone, and option D, Vasopressin, both refer to the same hormone that regulates water balance, not calcium reabsorption.

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.
