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 is responsible for dealing with the deoxygenate blood, while the left side deals with oxygenated blood. Systemic Circulation is the process of carrying oxygenated blood to the body, while the Pulmonary Circulation is the process of carrying oxy-gen depleted blood from the heart to the lungs.
