Detailed explanation-1: -The definition of stroke volume is the volume of blood pumped out of the left ventricle of the heart during each systolic cardiac contraction.
Detailed explanation-2: -Stroke Volume (SV) is the volume of blood in millilitres ejected from the each ventricle due to the contraction of the heart muscle which compresses these ventricles. SV is the difference between end diastolic volume (EDV) and end systolic volume (ESV).
Detailed explanation-3: -Stroke volume is the amount of blood the left ventricle pumps out in one cardiac cycle. This is around 70 ml. 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. This means that in one minute, a normal heart pumps about 5 litres of blood.
