Read the following Assertion and Reason and choose the correct option. Assertion: Henle's loop maintains high osmolarity of medullary interstitial fluid Reason: Reabsorption is minimum in the ascending limb of Henle's loop

Step-by-step solution

Henle's loop n plays a significant role in the maintenance of high osmolarity of medullary interstitial fluid. The descending limb of loop of Henle is permeable to water but almost impermeable to electrolytes. This concentrates the filtrate as it moves down.
