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 purpose of your heart is to pump blood to the organs and tissues of your body that need the oxygen and nutrients it carries.Oxygen-rich blood is pumped out of the left side of your heart (shown on the right in the diagram) into the arteries to these tissues and organs.our heart is made up of 2 pumps. The pump on the right hand side receives blood that has already delivered its oxygen round the body and sends this blood to the lungs to pick up more oxygen (and get rid of carbon dioxide).
