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.
Blood Vessels of the Heart. Blood supply to the heart is provided by the left and right coronary arteries. The left coronary artery arises from the aorta, passes between the left auricle and the pulmonary trunk to the coronary groove. It subsequently divides into the interventricular paraconal and circumflex branches.
