Respuesta :
70 ml would be the stroke volume (SV) every beat.
Given,
End Diastolic Volume(EDV) = 120 ml/beat
End Systolic Volume(ESV) = 50 ml/beat
According to the formula
Stroke volume = End Diastolic Volume(EDV) - End Systolic Volume(ESV)
Stoke volume = 120 ml/beat - 50 ml/beat
Stroke volume = 70 ml/beat
The amount of blood in the ventricles just before the heart contracts is known as end-diastolic volume.
End-systolic volume (ESV) is the amount of blood in a ventricle at the point where systole, or contraction, ends and diastole, or filling, begins.
At any time during the cardiac cycle, the ESV has the lowest blood volume in the ventricle.
The amount of blood that is pumped out of the left ventricle of the heart with each systolic cardiac contraction is referred to as the stroke volume.
