Question

If loop of Henle were absent from an individual nephron, which one of the following is to be expected?

1. A. The urine will be more dilute (Correct answer)
2. B. The urine will be more concentrated
3. C. There will be no urine formation
4. D. There will hardly be any change

Correct Answer

Option A — The urine will be more dilute

Detailed Solution & Explanation

The correct answer is The urine will be more dilute.

Key Points

• The loop of Henle creates a concentration gradient in the medulla through the counter-current multiplier mechanism.
• Without it, this gradient cannot be maintained and the urine produced will be more dilute (isotonic to blood).
