  1. Atria of heart are receiving chambers while ventricles pump the blood forcefully to all organs of body. Hence muscle mass around ventricles is thickened compared to that around atria.

  2. Stimulus for rhythmic contraction of heart originates inside auricular wall due to presence of sinoatrial node.

  3. Moreover, myocardium of both atria together form a functional syncytium and it remains completely separated from ventricular myocardial syncytium.
