Question

Given below are two statements:
Statements I: Concentrated urine is formed due to counter current mechanism in nephron.
Statement II: Counter current mechanism helps to maintain osmotic gradient in the medullary interstitium.
In the light of the above statements, choose the most appropriate answer from the options given below.

• A. Statement I is correct but Statement II is incorrect.
• B. Statement I is incorrect but Statement II is correct.
• C. Both Statement I and Statement II are correct.
• D. Both Statement I and Statement II are incorrect.

Answer 1

The Correct Option is C

Both assertions are accurate. The counter-current system within the nephron's loop of Henle creates an osmotic gradient in the medullary interstitium, crucial for the production of concentrated urine.
