Heart is a hollow muscular organ that pumps the blood through the circulatory system by rhythmic contraction and dilation. In vertebrates there may be 3 chambers [as in humans] with 2 artria and ventricles. The heart is positioned in the chest behind the breastbone, in front of trachea, esophagus and aorta and above the diaphragm. Two-third of heart lies in the left side of the chest.
