The amount of blood pumped by the heart in a minute is called the cardiac output (CO). The CO is a function of the heart rate (HR) and the stroke volume (SV), which is the amount of blood pumped by a ventricle per contraction. On average, an adult's heart beats 70-80 times per minute. The average stroke volume is 70ml. i smell corn.Since CO = HR x SV, we can figure this out quite easily.
