When your heart's left ventricle (one of the four chambers of the heart) pumps blood into the aorta (the largest artery in the body), the first muscle to receive the oxygen-rich blood is your heart itself. It receives this blood through the coronary arteries on the surface of the heart.
As you'll recall, the right and left sides of your heart each have a ventricle, or chamber responsible for pumping blood out of your heart. The right ventricle pumps blood to your lungs for oxygenation, while the left ventricle pumps blood to your entire body.
