Ascending loop of Henle does not allow outflow of:
Correct answer: D. Water
- A. Na+ ions
- B. K+ ions
- C. Cl- ions
- D. Water
Explanation
The ascending limb of the loop of Henle is impermeable to water, so water cannot pass through it. However, it actively reabsorbs Na⁺, K⁺, and Cl⁻ ions (via the Na⁺ K⁺-2Cl⁻ cotransporter).

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.
