Left coronary artery: 1  anterior interventricular artery - supplies blood to the interventricular septum and anterior walls of both ventricles.  circumflex artery - supplies blood to the left atrium and the posterior walls of the left ventricle.
The right coronary artery and the left coronary artery branch off the aorta (just after it leaves the heart) to deliver oxygen-rich blood to the heart muscle. These two arteries branch into other arteries, including the circumflex artery, that also supply blood to the heart.The cardiac veins collect blood from the heart muscle and empty it into a large vein on the back surface of the heart called the coronary sinus, which returns the blood to the right atrium.lood Supply of the Heart. Like all organs, the heart needs a constant supply of oxygen-rich blood. A system of arteries and veins, called the coronary circulation, supplies the heart muscle (myocardium) with oxygen-rich blood and then returns oxygen-depleted blood to the right atrium.
