Answer:
The volume of blood ejected by the left ventricle during a heartbeat is the stroke volume (SV). The volume of blood ejected by the left ventricle in each minute is the cardiac output (CO), which is equal to the heart rate (HR) multiplied by the stroke volume and therefore is measured in liters per minute
