Question:
Compare the statements A and B.
Statement A : When the urine moves through the descending limb, it becomes hypertonic and as it passes through the ascending limb of Henle's loop, it becomes hypotonic.
Statement B : The descending limb is permeable to sodium ions, while the ascending limb is impermeable to sodium ions.

- Statement A is wrong and B is correct.
- Statement A is correct and B is wrong
- Both statements A and B are correct.
- Both statements A and B are wrong
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
When the urine moves through the descending limb, it becomes hypertonic and as it passes through the ascending limb of the loop of Henle, it becomes hypotonic because the descending limb is permeable to water and impermeable to sodium ions, while the ascending limb is impermeable to water and permeable to sodium ions.

Excretory products and their elimination
The physiological process of the elimination of metabolic waste from the body is called excretion. The excretory products comprise amino acids, carbon dioxide, urea, uric acid, water, and ammonia. Some of the Molluscs and Echinoderms excrete waste products from the body in the form of amino acids. Ammonia is the foremost excretory product in animals, it is derived from the proteins exists in the food we eat.
