Urinary System Questions Questions
Question 1 of 5
With respect to sodium re-absorption:
Correct Answer: D
Rationale: Sodium reabsorption occurs in PCT (~70%), loop (ascending), and DCT (regulated) all apply. This encompasses Na+ handling, key for fluid balance, contrasting with single-segment focus.
