Descending limb/Ascending limb of loop of Henle is impermeable to water.

Text Solution

AI Generated Solution

**Step-by-Step Solution:** 1. **Understanding the Structure of the Loop of Henle**: The Loop of Henle consists of two main parts: the descending limb and the ascending limb. Each limb has different properties regarding permeability to water and solutes. 2. **Analyzing the Descending Limb**: The descending limb of the Loop of Henle is permeable to water. This means that water can move out of the descending limb into the surrounding interstitial fluid, allowing for water reabsorption. 3. **Analyzing the Ascending Limb**: In contrast, the ascending limb of the Loop of Henle is impermeable to water. This limb primarily transports sodium chloride (NaCl) out of the filtrate into the surrounding tissue, but does not allow water to follow. ...
