The heart is constructed of a special kind of muscle called the myocardium or cardiac muscle, and is enclosed in a double-layered, membranous sac known as the pericardium. A wall of muscle, the septum, divides the heart into two cavities.The left cavity pumps blood throughout the body, while the right cavity pumps blood only through the lungs. Each cavity is in turn divided into two chambers, the upper ones called atria, the lower ones ventricles.Venous blood from the body, containing large amounts of carbon dioxide, returns to the right atrium.he left cavity pumps blood throughout the body, while the right cavity pumps blood only through the lungs.
