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 ventricle on the right side of your heart pumps blood from your heart to your lungs. After your body's organs and tissues have used the oxygen in your blood, the vena â¦ cavae carry the oxygen-poor blood back to the right atrium of your heart.
