The counter-current mechanism in the loop of Henle is primarily responsible for maintaining a concentration gradient in the renal medulla. Which of the following best describes the osmolarity at the tip of the loop of Henle in the inner medulla?
- A.
- B.
- C.
- D.
Show correct answer & step-by-step solution
Correct answer: C —
Solution
- The loop of Henle creates a hyperosmotic environment in the renal medulla.
- The osmolarity of the filtrate increases as it descends into the medulla.
- At the tip of the loop of Henle, the concentration reaches its maximum value.
- This value is approximately .
- Hence the answer is (C).
