उत्तर
The human heart is four chambered consisting of two atria and two ventricles. The left side of the heart receives oxygen-rich blood whereas the right side of the heart receives carbon dioxide-rich blood. The left and right sides of the heart are completely separated from each other by a muscular septum, which prevents the mixing of oxygen-rich and carbon-dioxide rich blood.
