Detailed explanation-1: -The heart muscle, like every other organ or tissue in your body, needs oxygen-rich blood to survive. Blood is supplied to the heart by its own vascular system, called coronary circulation. The aorta (the main blood supplier to the body) branches off into two main coronary blood vessels (also called arteries).
Detailed explanation-2: -Oxygenated blood is pumped into the aorta from the left ventricle. This is where it enters the right and left main coronary arteries, and subsequent branching feeds the myocardial tissue of all four chambers of the heart (see Figure 7).
Detailed explanation-3: -Coronary arteries send blood to the heart muscle. All tissues in the body need oxygen-rich blood to function. The heart muscle also needs it. And oxygen-depleted blood must be carried away. The coronary arteries wrap around the outside of the heart.
