The heart is suppled by the first two branches of the aorta, the RIGHT and LEFT CORONARY ARTERIES.
The hearts walls are thick, thus needs blood to be supplied to the outside walls, and through diffusion from interior walls.
Right coronary artery- passed behind the pulmonary trunk to the coronary groove
Left coronary artery- runs between the pulmonary truck and left auricle and supplied a greater volume of the myocardium than the right coronary artery
