lub and dubb

lub produced during ventricular systole that is contraction of ventricle and it has louder sound since the blood should go to all parts of the body

dubb produced during joint diastole due to closing of semilunar valves and it has dull sound since it just goes to lungs


HOPE THIS HELPS YOU
