The active uptake of sodium from the ascending limb or thick loop of Henle is promoted by the action of :
Correct answer: B. Aldosterone
- A. ADH
- B. Aldosterone
- C. Concentration of Filtrate
- D. Vasopressin

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.
