How this entity was disambiguated
This entity first appeared as the object of triple T18088024 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

Target entity: atrioventricular nodal artery Context triple: [Atrioventricular node, bloodSupply, atrioventricular nodal artery]
-
A.
sinoatrial nodal artery
The sinoatrial nodal artery is the coronary artery branch that supplies blood to the heart’s natural pacemaker, the sinoatrial (SA) node.
-
B.
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.
-
C.
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.
-
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.
right coronary artery
The right coronary artery is a major coronary vessel that supplies oxygenated blood to portions of the right atrium and ventricle, the sinoatrial node, and often the atrioventricular node.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
