Which part of Henle's loop is permeable to water?
  1. Descending limb
  2. Ascending limb
  3. Both descending and ascending limb
  4. Neither descending nor ascending limb

Solution

The descending limb of Henle's loop is permeable to water but almost impermeable to electrolytes. This helps in concentrating the filtrate as it moves down. The ascending limb is impermeable to water but allows transport of electrolytes.
