Rationale: Urea enters via filtrate (A), concentrates in cortical collecting ducts as water exits (B), and thin loops/medullary ducts allow urea recycling (C). All are true—filtrate supplies urea, water reabsorption concentrates it, permeable segments recycle it—making E (all are correct), reassigned as D, correct.

Question 4 of 9

Which part of the Loop of Henle is more permeable to water?

Correct Answer: B

Rationale: The thin descending limb of the Loop of Henle is highly permeable to water due to its numerous aquaporin-1 channels, allowing water to exit into the hyperosmotic medullary interstitium, concentrating the filtrate. The thick ascending limb actively reabsorbs Na⁺ and Cl⁻ but is impermeable to water, diluting the filtrate. The thin ascending limb has limited water permeability, and there's no ‘thick descending limb,' making B the correct answer.
