chordae tendineae - string-like extensions of tough connective tissue that extend from the flaps of the atrioventricular valves to the papillary muscles circumflex artery - a branch of the left coronary artery; supplies most the left ventricle continuous capillary - most common type of capillary, found in virtually all tissues except epithelia and cartilage; contains very small gaps in the endothelial lining that permit exchange coronary arteries - first branches of the ascending aorta that supply blood to the heart; the left coronary artery feeds the left side of the heart, the left atrium and ventricle, and the interventricular septum; the right coronary artery feeds the right atrium, portions of both ventricles, and the heart conduction system coronary sinus - large, thin-walled vein on the posterior surface of the heart that lies within the atrioventricular sulcus and drains the heart myocardium directly into the right atrium coronary sulcus - sulcus that marks the boundary between the atria and ventricles coronary veins - vessels that drain the heart and generally parallel the large surface arteries elastic artery - (also, conducting a
