Stroke volume is the amount of blood pumped out by the left ventricle of the heart in one contraction. Usually, about two-thirds of the blood in the ventricle is expelled in each contraction. It is the difference between the end-systolic volume (ESV) and end-diastolic volume (EDV). In an adult human heart, ESV is approximately 50 ml and EDV is approximately 120 ml. Hence, the stroke volume is approximately 70 ml.
Thus, the correct answer is option B.
