Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: Left atrium to left ventricle
Concept:

The unidirectional flow of oxygenated blood on the left side of the heart is regulated by the mitral valve.

Formula:

None

Solution:

  • The bicuspid valve, also known as the mitral valve, is situated between the left atrium and the left ventricle.


  • It ensures that blood passes downwards into the ventricle and does not regurgitate back into the atrium during contraction.


Why other options are incorrect:

  • Right atrium to right ventricle: Controlled by the tricuspid valve.


  • Left ventricle to aorta: Controlled by the aortic semilunar valve.

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.
