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 pulmonary vein is the only vein to carry oxygenated blood which is on its way to the heart from the lungs. The diagram also shows you that the right and side of the heart, both atrium and ventricle, contains only deoxygenated blood.
