The heart is the vital organ in the human body located under the ribcage, pumps oxygenated blood to the whole body by taking it from the lungs and pumps back the deoxygenated blood from the body to the lungs for the removal of carbon dioxide. Normally the heart beats very min around 72 times and it has four chambers that contract and relax to regulate the normal pumping of the blood. The two upper chambers are known as atria or left and right atrium and the lower two chambers are known as ventricles or left and right ventricles.
