... Background: The heart is the body's most important organ. Without it nothing would work. The heart has the tiresome job of pumping blood around the body non-stop. Without it, the human race wouldn't exist. Some areas need more blood then others, so the body's veins and arteries siphon off the blood accordingly. The heart is a muscular organ which pumps blood around the blood vessels (the heart and blood vessels together are called the cardiovascular system). It is surrounded by the pericardial sac. This consists of an outer membrane (the pericardium) and the cavity (pericardial cavity) between it and the heart. This cavity is filled with a cushioning fluid (pericardial fluid). The heart has four chambers - two atria and two ventricles, all lined by a thin tissue layer called the endocardium. Oxygenated blood from the lungs is sent to the heart so it can be pumped all over the body.
