the contraction volume of the ventricles is always much increased , and the output per unit of time is generally augmented , and this together with the contraction of the peripheral arterioles causes an increase in the tension in the systemic circulation , an acceleration of the circulation , and possibly a temporary increase in the pressure in the great veins and in the auricle and ventricle in diastole ( kaufmann ) .
