The heart has three layers. they are the: epicardium: this thin membrane is the outer most layer of the heart. myocardium: this thick layer is the muscle that contracts to pump and propel blood.
Schematic diagram Of The Cardiovascular System
Schematic Diagram Of The Cardiovascular System Heart anatomy. the heart has five surfaces: base (posterior), diaphragmatic (inferior), sternocostal (anterior), and left and right pulmonary surfaces. it also has several margins: right, left, superior, and inferior: the right margin is the small section of the right atrium that extends between the superior and inferior vena cava . The base of the heart is located along the body's midline with the apex pointing toward the left side. because the heart points to the left, about 2 3 of the heart's mass is found on the left side of the body and the other 1 3 is on the right. anatomy of the heart pericardium. the heart sits within a fluid filled cavity called the pericardial. The epicardium covers the heart, wraps around the roots of the great blood vessels, and adheres the heart wall to a protective sac. the middle layer is the myocardium. this strong muscle tissue powers the heart’s pumping action. the innermost layer, the endocardium, lines the interior structures of the heart. 2. Heart, organ that serves as a pump to circulate the blood. it may be a straight tube, as in spiders and annelid worms, or a somewhat more elaborate structure with one or more receiving chambers (atria) and a main pumping chamber (ventricle), as in mollusks. in fishes the heart is a folded tube, with three or four enlarged areas that correspond.
