Given below are two statements: Statement 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.
Detailed Solution
The counter current flow of filtrate through the loop of Henle and blood through the vasa recta helps maintain an increasing osmolarity towards the inner medullary interstitium, and this counter current mechanism is what enables the formation of concentrated urine. Both statements are correct.
