The coronary arteries supply blood to the myocardium (heart tissue) itself: e.g., coronary capillaries deliver oxygenated blood (nutrients) to all of the heartâs cells.
In essence, the left main coronary artery supplies the left atrium, interventricular septum, left ventricle and the anterior wall of the right ventricle. On the other hand, the right coronary artery supplies the right atrium, the right ventricle as well as the sino-atrial node. Interestingly, coronary blood flow can be described as a phasic flow.
