</u>
Explanation:
CARDIAC EXPENSE, is the amount of blood that the ventricles propel every minute.
<u>
Cardiac output = ejection volume X heart rate
</u>
<u />
Cardiac output is modified by changing the volume that is expelled in each beat (<em>ejection volume or systolic volume</em>), or by changing the heart rate.
<em>The heart covers a wide range of blood flow demands. Cardiac output can range from 5 to 30 L / min, depending on the activity of the organism.</em>
