TRUE statement about right coronary aery is-
Right coronary aery is smaller than Left coronary aery (Right side of myocardium is thinner compared to left). Arises from anterior aoic sinus (Left coronary aery arises from Left posterior coronary sinus) Right coronary aery runs in the right anterior coronary sulcus, & winds around the inferior border of the hea. It runs backwards in the right posterior coronary sulcus to reach posterior interventricular groove. Middle cardiac vein and posterior interventricular aery lies in the posterior interventricular groove. Right coronary aery terminate by anastomosing with circumflex branches of LCA.
Diameter less than LCA
RCA gives anterior interventricular aery
RCA supplies major pa of left atrium and left ventricle
RCA gives rise to circumflex coronary branch
