In nephrons, counter-current multiplier occurs at:
Correct answer: A. Loop of Henle
- A. Loop of Henle
- B. Collecting Duct
- C. Bowman's Capsule
- D. Glomerulus
Explanation
The counter‑current multiplier system operates in the loop of Henle, where the opposing flow of fluid in the descending and ascending limbs creates and maintains a concentration gradient in the renal medulla, enabling water reabsorption and urine concentration.

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.
