The heart is a vital organ located in the center of the chest with a slight tilt to the left. Using rhythmic muscle contractions, it circulates blood through veins and arteries, which supplies tissues with oxygenated blood and disposes waste.
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.
