Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: Leakage of fluid from blood vessels
Concept:

Inflammation requires the movement of plasma and immune cells from the bloodstream into the damaged tissue.

Formula:

None

Solution:

  • Bradykinin is a potent inflammatory mediator peptide.


  • Its primary vascular role is to cause the endothelial cells of the capillaries to pull apart slightly.


  • This drastically increases capillary permeability, resulting in the rapid leakage of fluid from blood vessels into the surrounding tissue space, clinically presenting as swelling (edema).


Why other options are incorrect:

  • Constriction / Blockage: Bradykinin causes intense vasodilation (widening), not constriction or clotting.

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.
