The heart is an organ located just behind and slightly to the left of the breastbone, and pumps blood through a network of veins and arteries known as the circulatory system. The right atrium is sent blood from the veins, and delivers it to the right ventricle. It's then pumped into the lungs where it is oxygenated. The left atrium is sent oxygen enriched blood from the lungs and delivers it to the left ventricle, where it's then pumped throughout the body, and the ventricular contractions create blood pressure.
