Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: Pulmonary vein
Concept:

The pulmonary circulation operates oppositely to the systemic circulation in terms of oxygen content within vessels.

Formula:

None

Solution:

  • Veins generally carry blood toward the heart.


  • The pulmonary veins carry newly oxygenated blood from the capillary beds of the lungs back to the left atrium of the heart.


Why other options are incorrect:

  • Pulmonary artery: Carries deoxygenated blood away from the heart to the lungs.


  • Coronary artery: Supplies oxygenated blood to the heart muscle itself.
