How this entity was disambiguated
This entity first appeared as the object of triple T18088003 — resolving that mention is where its identity was fixed.

Target entity: right atrium Context triple: [Atrioventricular node, locatedIn, right 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.
Left atrium
The left atrium is one of the heart’s four chambers that receives oxygen-rich blood from the lungs and passes it to the left ventricle for systemic circulation.
-
C.
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.
-
D.
Tricuspid valve
The tricuspid valve is one of the heart’s four valves that regulates blood flow between the right atrium and right ventricle, preventing backflow during ventricular contraction.
-
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.
