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.
The heart muscle itself gets its blood supply from the coronary arteries. The left coronary artery and its branches, the left anterior descending artery and circumflex artery, supply blood to the chambers on the left side of the heart. This animation shows you where these arteries are located.
