Interesting question. I'd presume that as the heart is constantly pumping blood, the oxygen in the blood will diffuse into the cells that make up the inner part of the muscle of the heart. This is a slow process, however, and the heart needs a lot of oxygen, so it has arteries on the outside of it. This would mean the heart muscle is getting a rich supply oxygen from both sides of the muscular wall, allowing it to work as efficiently as it does.
The arteries that actually serve the heart itelf are known as coronary arteries.
arteries
Pulmonary arteries carry oxygenated blood away from the heart. Veins carry blood to the heart.
There are two main arteries that feed the heart. They are called the coronary arteries. These are the arteries that receive bypass surgery. The number of bypasses is determined by the number of blockages, not the number of arteries.
The arteries
arteries and veins are found throughout the body. arteries carry blood away from the heart and veins carry it to the heart
yes
Coronary arteries and veins are found on the surface of the heart, branching out across the myocardium (muscle tissue of the heart). The coronary arteries supply oxygen-rich blood to the heart muscle, while the coronary veins collect oxygen-depleted blood from the heart muscle and return it to the circulation.
Smooth
False. Oxygenated blood is found in the systemic arteries, which carry blood away from the heart to the body, but not in the pulmonary arteries, which carry blood from the heart to the lungs for oxygenation.
there are many and they are located like fingers cradling the heart all over the outside

elastic tissue
The myocardium receives its oxygen and nutrients from the coronary arteries, which lie on the outside of the heart.
