Heart is a hollow muscular organ that pumps the blood through the circulatory system by rhythmic contraction and dilation. In vertebrates there may be up to four chambers (as in humans), with two atria and two ventricles.
The heart is a pump, which moves the blood. The arteries and veins are the pipes through which the blood flows.
