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.
Because the arteries have to carry blood to the heart
because they cant do what their job is inside so they need to be out
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
They are found on the wall of the heart itself
Smooth
The coronary arteries are located on the surface of the heart, branching off from the aorta. They supply the heart muscle with oxygenated blood to support its function.

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

The renal arteries connect the kidney and the heart.
