The Circumflex Branch and the Anterior Interventricular Artery are Branches

Question

The circumflex branch and the anterior interventricular artery are branches of the
A) right coronary artery.
B) left coronary artery.
C) interventricular artery.
D) coronary sinus.
E) aorta.

Accepted Answer

The circumflex branch and the anterior interventricular artery are both branches of the left coronary artery, one of the two main branches of the coronary arteries that supply the heart with oxygenated blood. The right coronary artery also supplies blood to the heart, but it does not give rise to these specific branches. The interventricular artery is a general term for any artery that supplies blood to the ventricles, and the coronary sinus is a vein that drains the heart's blood into the right atrium. The aorta is the main artery that carries oxygenated blood out of the heart to the rest of the body, but it does not supply blood to the heart itself.
