$SA$ node

Vedclass · Answer

(A) The heart is myogenic,meaning its rhythmic contractions are initiated by specialized cardiac muscle cells. The $SA$ (Sinoatrial) node,located in the right atrium,acts as the natural pacemaker of the heart. It generates electrical impulses that spread through the heart,initiating and maintaining the rhythmic contraction of the cardiac muscle. Therefore,the $SA$ node is responsible for initiating and maintaining the heartbeat.
