Document Summary
Describe the location and functional anatomy of the heart: location: the heart lies in the mediastinum, an anatomical region that extends from the sternum to the vertebral column, between the lungs, functional anatomy, pericardium: surrounds and protects heart. 2 layers: fibrous pericardium: serous pericardium. Between layers consists of the pericardium cavity that contains serous fluid to reduce friction: layers of the heart wall. Epicardium: 2 layers, visceral layer of the serous pericardium, layer of delicate fibro-elastic tissue and adipose tissue. Myocardium: responsible for pumping action of the heart and is composed of cardiac muscle tissue. Endocardium: thin layer of endothelium overlying a tin layer of ct, provides smooth lining for the chambers and covers the valves of the heart, 2.
