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.
From the left atrium blood comes to the left ventricle. Left ventricle sends this oxygenated blood through aorta and arteries to all organs of the body. The following diagram shows blood flow through the heart. Here the blue arrows show the flow of de-oxygenated blood. See, the two blue arrows come to the right atrium (2). This is the chamber, which receives the de-oxygenated blood from the body.
