Document Summary
In the mediastinum between second rib and fifth intercostal space. Two-thirds to the left of the midsternal line. Anterior to the vertebral column, posterior to the sternum. Parietal layer ( pericardium ) a clear fibrous bag protecting & anchoring heart. Visceral layer (epicardium) on external surface of the heart. Very thin layer of fluid between the layers - decreases friction. Coronary sulcus (atrioventricular groove) encircles junction of atria and ventricles. Anterior & posterior interventricular sulci on external surface suggest location of septum inside. Right side pumps blood to & through pulmonary (lung) arteries & veins. Left side pumps blood to & through systemic arteries & veins (everything but lungs) Systemic veins right atrium tricuspid valve right ventricle. Right ventricle pulmonary (semilunar) valve pulmonary trunk pulmonary arteries lung capillaries. Pulmonary veins left atrium mitral valve left ventricle. Left ventricle aortic (semilunar) valve ascending aorta systemic arteries systemic capillaries. Equal volumes of blood are pumped to the pulmonary and systemic circuits.
