What would be the cardiac output of a person if the blood volume in each ventricle is 120 mL at the end of diastole and 50 mL at the end of systole and the heart rate is 60 beats per minute?

Stroke volume            =   End diastolic volume – end systolic volume                                         =   120 mL – 50 mL = 70 mLCardiac output          =   stroke volume x heart rate                                         =   60 x 70Stroke volume            =   4,200 mL
