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: -Ventricular stroke volume (SV) is often thought of as the amount of blood (mL) ejected per beat by the left ventricle into the aorta (or from the right ventricle into the pulmonary artery).
