Sino-auricular node is called pacemaker of our heart. Why?
Sino-auricular node is called pacemaker, because nerve impulse or wave of contraction starts from it and goes to both auricles. Since the SA node initiates and maintains the rhythmicity of the heart and maintains the pace of the heart beat, it is known as the natural pacemaker of the human body.
