alleryCardiac output is BEST defined as
APulmonary plus systemic blood volumes
BEnd diastolic ventricular blood volume
CVolume of blood ejected per beat
DStroke volume times heart rate per minute
Answer & Solution
Correct answer: D. Stroke volume times heart rate per minute
Cardiac output = stroke volume x heart rate.
With typical values (70 mL per beat x 72 beats/min) it equals about 5 litres per minute in a healthy adult.
Athletes show much higher values during exercise.
