The heart is a muscular organ about the size of a fist, located just behind and slightly left of the breastbone. The heart pumps blood through the network of arteries and veins called the cardiovascular system. The right atrium receives blood from the veins and pumps it to the right ventricle.
The heart is located in the chest cavity. It is surrounded by a covering called the pericardium. The heart itself is divided into four chambers, called the right and left atria and the right and left ventricles. The heart is connected to the rest of the body by means of VEINS which return to the lungs and the ARTERIES which pump blood to the body.
