    Anatomy of the heart

    The heart is a hollow muscular organ located in the thoracic cavity between the lungs just behind the sternum.

    Layers of the heart

    Endocardium - the innermost layer of the heart.  It forms the lining and folds back onto itself to form the four valves.  It is in this layer that the conduction system is found.

    Myocardium - the middle and contractile layer of the heart.  It is made up of striated muscle fibers interspersed with intercalated disks.

    Epicardium – the outermost layer of the heart.  It is actually the inner (visceral) layer of the pericardium.

    The Pericardium

    The pericardium is a sac in which the heart is contained. It consists of the outermost fibrous pericardium and the serous pericardium which consists of a visceral and a parietal portion. The visceral layer invests the heart and is also called the epicardium. The parietal layer lines the fibrous pericardium.  Between the visceral and parietal layers is a serous fluid which serves to prevent friction as the heart beats.

    The Heart Chambers

    Right Atrium – receives deoxygenated blood returning to the heart from the body via the superior vena cava which carries blood from the upper body and the inferior vena cava which carries blood from the lower body.

    Right ventricle – receives deoxygenated blood from the right atrium which it pumps to the lungs for oxygenation through the pulmonary artery (trunk) to the right and left pulmonary arteries.

    The pulmonary arteries are the only arteries in the body the carry deoxygenated blood.

    Left atrium – receives oxygenated blood returning from the lungs via the right and left pulmonary veins. 

    The pulmonary veins are the only veins in the body that carry oxygenated blood.

    Left ventricle – receives the oxygenated blood from the left atrium and pumps it to the body through the aorta, the largest artery of the body.

    The heart is actually a two-sided pump separated by a septum.  The upper chambers consist of the right and left atria (singular: atrium); the lower chambers are the right and left ventricles.  The chambers pump simultaneously – both atria contract together then the two ventricles.

    Beginning with the right atrium, trace the normal pathway of blood flow through
