The coronary arteries.
Coronary arteries are the vessels that provide blood supply to the heart muscle itself. If they are blocked or damaged, a heart attack may result.
Interestingly, none of the blood pumped THROUGH the heart provides circulation TO the heart itself. The heart muscle has its own set of arteries and veins (such as the descending and circumflex) from which to obtain oxygen and nutrients.
Coronary arteries branch from the aorta and supply the heart muscle.
Heart attacks or myocardial infarctions are caused by blockages of the coronary arteries or the blood vessels that provide the blood supply to the heart muscle itself.
There are several things that are found in the walls of the stomach uterus and arteries. The smooth muscle is one of elements that are found in these organs.

The first vessels that branch off the aorta are called the coronary arteries. These arteries are so important for the heart muscle to work properly that they are the first off the aorta.These arteries give blood to the heart muscle itself. These arteries are also called coronary arteries because they form a crown around the top of the heart with the arteries forming an upside down crown.
The coronary arteries carry oxygenated blood to the heart itself. These arteries supply the heart muscle with oxygen and nutrients.

Blood is oxygenated in the lungs travels through the pulmonary veins into the heart. The heart muscle itself receives oxygenated blood through through the coronary arteries that branch off from the aorta.
Two coronary arteries branch off of the ascending aorta immediately upon exiting the heart. These two arteries (and their branches) are what nourish the cardiac muscle itself.
Heart attacks or myocardial infarctions are caused by blockages of the coronary arteries or the blood vessels that provide the blood supply to the heart muscle itself.
