A) Brachiocephalic arteries
B) Right and left coronary arteries
C) Right and left subclavian arteries

E) Right and left pulmonary arteries

Aortic Semilunar Valves

Valves located between the aorta and the left ventricle of the heart that prevent blood from flowing back into the heart.

Great Cardiac Veins

The great cardiac veins are large veins on the surface of the heart that drain blood from the heart muscle.

Coronary Arteries

The arteries that supply oxygen-rich blood to the heart muscle itself, crucial for heart function.
