Four corners define by points projected onto anterior thoracic wall: right pulmonary surface, diaphragmatic surface, left pulmonary surface, anterior surface, deep to sternum and ribs. Right from great vessels to diaphragm: fibrous pericardium. Keeps it from overfilling with blood: serous pericardium. Parietal layer: outer layer of serous pericardium, adhered to fibrous pericardium. Visceral layer/epicardium (associated with organs: inner layer of serous, adhered to surface of the heart, aka epicardium. Myocardium is heart muscle part that does the work, it contracts. Endocardium lines the heart: one layer of cells. Auricles are flaps going over atria: increase capacity of atrium. Coronary sulcus (groove: horizontal groove that encircles the top of the heart. Goes all the way around: distinguishes between atrium and ventricles.
