Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Efferent arteriole
Concept: Renal microvascular arrangement.

Solution: Blood enters the glomerulus via the afferent arteriole and exits via the narrower efferent arteriole, which maintains high hydrostatic pressure within the glomerular capillaries.

Why other options are incorrect:
  • Option B: The afferent arteriole supplies unfiltered blood into the glomerulus.

  • Option C: The renal vein drains fully processed venous blood from the kidney back to the vena cava.

  • Option D: Peritubular capillaries branch from the efferent arteriole to surround the cortical tubules.

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.
