Question

If loop of Henle is absent from mammalian nephron which of the following is expected?

• A. Urine will be more concentrated
• B. Urine will be more diluted
• C. No urine formation
• D. No change in quality and quantity

Answer 1

The correct option is B Urine will be more diluted

The loop of Henle is a U-shaped, long tubule consisting of a descending and an ascending limb. The descending limb is highly permeable to water and the ascending limb is impermeable to water but is permeable to ions. The main function of the loop of Henle is to concentrate the urine, regulating the amount of water to be given out. Hence, the urine will be more dilute if the loop of Henle is absent from mammalian nephron.

So, the correct answer is option B.
