Compare the statement A and B.
Statement A: When the urine moves through the descending limb, it become 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 impemeable to sodium ions.
- A Statement A is correct and B is incorrect.
- B Statement A is wrong and B is correct.
- C Both statements A and B are incorrect
- D Both statement A and B are correct.
Answer & Solution
Correct Answer
(A) Statement A is correct and B is incorrect.
Step-by-step Solution
Detailed explanation
(A) Statement A is correct and B is incorrect.,
The descending limb of Henle's loop is permeable to water, allowing it to leave, which makes the filtrate hypertonic. The ascending limb is impermeable to water but activity transports electrolytes out, making the filtrate hypotonic. Therefore, statement A is correct but Statement B is incorrect as the descending limb is impermeable to sodium ions while ascending limb is permeable to Na ions.
