Question

Quizplus · Accepted Answer

The ejection fraction represents the percentage of blood volume within a ventricle that is pumped out during systole (when the heart contracts). It is calculated by dividing the stroke volume (the amount of blood pumped out of the ventricle with each beat) by the end-diastolic volume (the amount of blood in the ventricle just before it contracts). Therefore, options A and B are not correct as they refer to the total blood volume pumped by the ventricle, rather than the percentage of blood within the ventricle. Option D is also not correct as the ejection fraction specifically measures the amount of blood ejected during systole, not diastole.
