The heart receives its own supply of blood from the coronary arteries. Two major coronary arteries branch off from the aorta near the point where the aorta and the left ventricle meet. These arteries and their branches supply all parts of the heart muscle with blood.
Instead, it gets its blood supply during the diastolic cycle, after the ventricles (and the entire heart) have relaxed. This circuit is from the base of the aorta, through the coronary arteries, through the heart muscle itself, through the coronary veins, and back to the base of the superior vena cava.
