A Dr. Mehmet Oz, MD , Cardiology (Cardiovascular Disease), answered. The heart gets its own supply of blood from the coronary arteries. The two main coronary arteries (right and left) and their branches supply blood throughout the heart muscle. This animation explains how these arteries transport blood.
The largest artery from the heart is called the aorta. This artery branches into smaller and smaller vessels before finally reaching the tiny capillaries where oxygen and nutrients are delivered to organs and tissues. The other main artery from the heart goes to the lungs where its blood picks up oxygen.Veins are the blood vessels that carry blood back to the heart. They have much thinner walls than arteries and are under less pressure.he other main artery from the heart goes to the lungs where its blood picks up oxygen.
