right coronary artery

artery that lies in the right atrioventricular sulcus and has branches that supply the posterior and anterior surfaces of the ventricular muscle another branch that supplies the tissues of the heart

marginal artery

branch of the right coronary artery passes along the inferior border of the heart

left coronary artery

one of the branches that supplies the tissues of the heart

Anterior Inteventricular Artery

Branch of the left coronary artery Also known as left anterior descending artery Also known as anterior descending artery l Lies in the anterior interventricular sulcus and has branches that supply walls of both ventricles

Circumflex artery

Branch of the left coronary artery Branch that follows the anterior atrioventricular sulcus between the left atrium and the left ventricle and has branches that supply the left atrium and left ventricle

coronary sinus

Large vein in the posterior atrioventricular sulcus that empties into the right atrium.

great cardiac vein

Vein that is located in the anterior interventricular sulcus near the anterior interventricular artery

middle cardiac vein

Vein that parallels the posterior descending right coronary artery on the posterior surface of the heart

Ascending thoracic aorta

Vessel that contains the right and left coronary orifices

posterior interventricular artery

another branch of the right coronary artery inferior extension of the right coronary artery on the posterior surface of the heart travels along the posterior interventricular sulcus and supplies the walls of both ventricles
