Answer:
Cardiac output = ejection volume X heart rate
Step-by-step explanation:
CARDIAC EXPENSE, is the amount of blood that the ventricles propel every minute.
Cardiac output = ejection volume X heart rate
Cardiac output is modified by changing the volume that is expelled in each beat (ejection volume or systolic volume), or by changing the heart rate.
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.
