The ejection fraction (EF) typically refers to the amount of blood pumped out of the left ventricle each time it contracts (as measured by doing echocardiogram.) It is expressed as a percentage of the ratio of stroke volume to the end-diastolic volume as follows: EF = Stroke Volume / End-Diastolic Volume. Please answer the question that follows: The ejection fraction for an individual whose stroke volume is 44 ml, and end- diastolic volume is 110 ml of blood, would be _. This would meet the body's demand for blood flow. 40%; inadequately 75%; adequately 60%; adequately 10%; inadequately
