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 right side of the heart collects and delivers oxygen-poor blood to the lungs and the left side of the heart collects and delivers oxygen-rich blood to the rest of the body, which is why the left ventricular wall is thicker and stronger than the right due to higher force needed to do the work.
