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.
The heart also needs a supply of blood for its nourishment. It does not use the blood it pumps for itself. The blood flowing through the heart does not directly serve the heart. Like all other organs the heart muscle has its own blood circuit. The heart gets blood from the coronary arteries that emerge directly from the aorta.
