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.
  Veins take blood to the heart, arteries take blood away from the heart. The vessels that carry blood to the heart are called veins. Those that supply the body with blood â¦ from the heart are called arteries.Examples are the jugular veins that return blood from the head, and the carotid arteries that supply blood to the head.wo other heart valves separate the ventricles and the large blood vessels that carry blood leaving the heart.
