<prompt> All of the following statements are false EXCEPT:Right ventricle work more than left ventricleLeft ventricle works more than right ventricleBoth ventricle work equalMaximum ventricular filing occurs in isovolumetric contraction  <response>: Ans. B Left ventricle works more than right ventricleRef: Guyton Physiology, 11th ed. pg. 110 Right ventricular external work output is normally about one sixth the work output of the left ventricle because of the six-fold difference in systolic pressures that the two ventricles pump.
