Is there blood circulation in the coronary arteries?

Yes, except. Yes, except in areas of infarction where the myocardial cells have died. Infarcted myocardium is dead heart tissue. This is usually the result of a myocardium infarction, mi, or heart attack. The purpose of a cardiac intervention: balloon angioplasty or stent, is to save this tissue before the process becomes irreversible.
Coronary arteries. If there isn't blood circulation in the coronary arteries, you die. There most certainly is normally circulation of blood in the coronaries.

Where do coronary arteries empty their blood?

Heart Muscle. The coronary arteries arise from the aorta and course over the surface of the heart. They supply blood to the heart muscle with nutrients and terminate in small connections called capillaries with heart veins. The health of these vessels is very important. If they become "clogged" with cholesterol plaque then the blood suppy to the heart is reduced leading to chest pain and heart attacks. Read more...
