NEET Biology question
Read the given statements and identify the structure referred to here. (i) Reabsorption in this region is minimum (ii) This region plays a significant role in the maintenance of high osmolarity of interstitial fluid (iii) Its descending limb is permeable to water but almost impermeable to electrolytes (iv) Its ascending limb is impermeable to water but allows transport of electrolytes actively or passively
Answer: (B)
Solution
All four characteristics — minimal reabsorption, maintenance of medullary osmolarity, a water-permeable descending limb and an electrolyte-transporting ascending
