Answer:
70 ml/beat.
Explanation:
Stroke volume may be defined as the volume of the blood that are pumped by the left ventricle in one contraction. The blood output can also be determined by knowing the stroke volume.
The stroke volume can be calculated by the formula as follows:
Stroke volume = End diastolic volume - End systolic volume
Here, end diastolic volume = 120 and end systolic volume = 50.
Stroke volume = 120 - 50
Stroke volume = 70 ml/ beat.
Thus, the answer is 70 ml/ beat.
