Document Summary
Outline: describe the orientation and location of the heart in the thorax. Sits to the left of the center of the chest and on top of the diaphragm. Cardiovascular system: describe the structural coverings of the heart; distinguish between the fibrous pericardium, parietal pericardium, and visceral pericardium. Fibrous pericardium is the outer layer of sac that anchors the heart and prevents overfilling. Parietal pericardium is the inner layer of the sac and secretes serous fluid. Visceral pericardium is the outer layer of the heart and secretes serous fluid, this is the epicardium. The parietal and visceral pericardium are serous membranes because they line the pericardial cavity and produce serous fluid: identify the layers of the heart wall. Visceral pericardium (epicardium) is the outer layer of the heart. Myocardium is the middle layer of the heart made of cardiac muscle tissue.
