Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Tricuspid valve
Concept:

Atrioventricular valves guard the openings between the upper and lower chambers of the heart.

Formula:

None

Solution:

  • Deoxygenated blood arriving in the right atrium must flow down into the right ventricle to be pumped to the lungs.


  • The portal between the right atrium and right ventricle is guarded by a one-way valve with three cusps.


  • This is definitively known as the tricuspid valve.


Why other options are incorrect:

  • Bicuspid (Mitral) valve: Located on the left side of the heart.


  • Septums: These are solid muscular walls that prevent communication (mixing) between the left and right sides of the heart.

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.
