stroke volume

Explanation:
Detailed explanation-1: -Stroke volume is the amount of blood the left ventricle pumps out in one cardiac cycle. This is around 70 ml. Cardiac output is the volume of blood pumped out by each ventricle per minute. Now to get cardiac output, we have to multiply stroke volume with the normal heart rate of 72 beats/min and we get 5, 040 ml/min.
Detailed explanation-2: -The volume of blood in the left ventricle at the end of ventricular filling is called the end-diastolic volume (EDV), which is about 120 mL in the adult human.
