Renal System Practice Questions Questions
Question 1 of 5
Match the description 'Active transport of sodium; impermeable to water' to the structure: A) proximal convoluted tubule, B) descending limb of the nephron loop, C) collecting duct, D) ascending limb of the nephron loop.
Correct Answer: D
Rationale: The ascending limb (D) actively transports sodium via Na/K/2Cl pumps and is impermeable to water, diluting filtrate. The proximal tubule (A) reabsorbs water, descending limb (B) is water-permeable, and collecting duct (C) varies with ADH, making D the match.

Which of the following is found in the renal medulla?
Correct Answer: D
Rationale: The loop of Henle (D) extends into the renal medulla, aiding concentration. Pacemaker cells (A) are cardiac, islets (B) are pancreatic, and DCT (C) is cortical, making D the medullary structure.
