Coronary Arteries

The coronary vessels, Latin: Arteriae coronariae, are those that supply the heart muscle with blood blood vessels. They circle the heart like a crown, hence the name "coronary".

They're filled in the [systole, systolic] of the heart. They are Endarteria. When these vessels are transferred, the heart attack occurs.
