Question

If Henle's loop were absent from mammalian nephron, which of the following is to be expected:

• A. There will be no urine formation
• B. There will be hardly any change in the quality and quantity of urine formed
• C. The urine will be more concentrated
• D. The urine will be more dilute

Answer 1

Answer: (D)

The urine will be more dilute

Answer 2

If Henle's loop (loop of Henle) were absent from a mammalian nephron, it would have a significant impact on urine formation. Henle's loop plays a crucial role in the concentration of urine by creating an osmotic gradient in the renal medulla, which allows for the reabsorption of water from the collecting duct. Without Henle's loop, the urine would be more dilute because the nephron would not be able to concentrate it effectively.

So, the correct answer is (D): The urine will be more dilute.
