How this entity was disambiguated
This entity first appeared as the object of triple T18021127 — resolving that mention is where its identity was fixed.

Target entity: Left atrium Context triple: [Pulmonary veins, transportTo, Left atrium]
-
A.
Right ventricle
The right ventricle is one of the heart’s four chambers that pumps deoxygenated blood to the lungs via the pulmonary artery.
-
B.
Atrial septum
The atrial septum is the wall of tissue that separates the heart’s left and right atria, helping maintain proper direction and separation of blood flow between them.
-
C.
Atrioventricular node
The atrioventricular node is a specialized cluster of cardiac cells that relays and delays electrical impulses between the atria and ventricles to coordinate the heart’s rhythm.
-
D.
Pulmonary artery
The pulmonary artery is the large blood vessel that carries deoxygenated blood from the right ventricle of the heart to the lungs for oxygenation.
-
E.
Sinoatrial node
The sinoatrial node is the heart’s natural pacemaker, a specialized cluster of cells that initiates and regulates the heartbeat by generating electrical impulses.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
