Two major coronary arteries branch off from the aorta near the point where the aorta and the left ventricle meet. These arteries and their branches supply all parts of the heart muscle with blood. The left main coronary artery branches into:
1 The pulmonary artery carries blood from the right side of the heart to the lungs to pick up a fresh supply of oxygen. 2  The aorta is the main artery that carries oxygen-rich blood from the left side of the heart to the body. 3  The coronary arteries are the other important arteries attached to the heart.he left side of the heart receives the oxygen-rich blood from the lungs and pumps it to the body. The heart has four chambers and four valves and is connected to various blood vessels. Veins are blood vessels that carry blood from the body to the heart.
