C
Peritubular capillaries
D
Bowman's space

Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: Collecting duct
Concept: Nephron tubular flow path.

Solution: Multiple distal convoluted tubules drain their final filtrate into a single shared collecting duct, which carries urine down through the renal medulla to the renal pelvis.

Why other options are incorrect:
  • Option A & Option C: Efferent arterioles and peritubular capillaries belong to the renal vascular network, not the urine-conducting tubular lumen.

  • Option D: Bowman's space is located at the start of the nephron.

Quality & Fidelity Assurance: Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
