Document Summary

Transport system pump; hollow blood vessels provide delivery routes. Extends obliquely for 12-14 cm from the 2nd rib to the 5th intercostal space; 2/3 of mass on left side; right side lying on diaphragm. Broad at base directed toward right shoulder, apex points toward left hip. Secrete serous uid to pericardial cavity ( ood ltrate minus proteins, very watery) Branching cardiac muscle cells arranged into bundles and the connective tissue wrappings of these bundles. Reinforce myocardium internally and anchor cardiac muscle bres. Provide additional support for great vessels and valves. Direct spread of action potentials across heart to speci c pathways. Layer of endothelium and connective tissue layer on inner myocardial surface. Continuous with endothelium of vessels leaving and entering heart. 2 exterior grooves: coronary sulcus (atroventricular groove) and anterior-posterior inter ventricular sulcus. Small thin walled - need only convey blood to ventricals. Deoxygenated, systemic blood enters right atrium via. Superior vena cava: systemic from above the diaphragm.
