The left coronary artery, the most abundant blood supply, feeds the left ventricular myocardium, which is more muscular and does most of the heart's work. The posterior and anterior interven-tricular arteries supply blood to the walls of both ventricles. The circumflex artery supplies blood to the walls of the left atrium and left ventricle.
