The pumping of the heart is caused by alternating contradictions and relaxation of the myocardium .These contradictions are stimulated by electrical impulses from a neutral peacemaker .The sinoartrial or S-a node causes the two artria to contract,forcing blood into the ventricles.Contradiction of the ventricles is controlled by impulses from AV valve located at the junction of the two atria.After the contraction ,the ventricles relax ,and pressure within them falls.
