As we have learned

Cardiac Output -

The stroke volume multiplied by the heart rate (number of beats per min.) gives the cardiac output.

- wherein

The cardiac output can be defined as the volume of blood pumped out by each ventricle per minute and averages 5000 mL or 5 litres in a healthy individual. The body has the ability to alter the stroke volume as well as the heart rate and thereby the cardiac output. For example, the cardiac output of an athlete will be much higher than that of an ordinary man.
