If the hea rate is 70 beats/min, then the cardiac output of this ventricle is closest to
Correct Answer: 5.25 L/min
Description: Stroke volume is the volume ejected from the ventricle and is represented on the pressure-volume loop as phase 2 - 3; End-diastolic volume is about 140 mL and end-systolic volume is about 65 mL; The difference, or stroke volume, is 75 mL. Cardiac output is calculated as stroke volume x hea rate or 75 mL x 70 beats /min = 5250 mL/min or 5.25 L/min
