WebCoronary arteries supply blood to the heart muscle. Like all other tissues in the body, the heart muscle needs oxygen-rich blood to function. Also, oxygen-depleted blood must be carried away. The coronary arteries wrap around the outside of the heart. Small branches dive into the heart muscle to bring it blood. WebBlood supply to the heart Because of the watertight lining of the heart (the endocardium) and the thickness of the myocardium, the heart cannot depend on the blood contained in its own chambers for oxygen and nourishment. It possesses a vascular system of its own, called the coronary arterial system.
