The part of renal tubule which is impermeable to water is: (A) Descending limb of loop of Henle (B) Ascending limb of loop of Henle (C) PCT (D) Collecting duct
Understand the Problem
The question is asking which part of the renal tubule does not allow water to pass through. It provides multiple choice answers related to kidney physiology.
Answer
Ascending limb of loop of Henle
The part of the renal tubule which is impermeable to water is the ascending limb of the loop of Henle.
Answer for screen readers
The part of the renal tubule which is impermeable to water is the ascending limb of the loop of Henle.
More Information
The ascending limb of the loop of Henle is designed to reabsorb ions without water following, which is crucial for creating the concentration gradient necessary for later stages of urine concentration.
Tips
A common mistake is to confuse the descending and ascending limbs. The descending limb is permeable to water, while the ascending limb is not.
