Explanation:
The amount of blood that the heart pumps per minute through the circulatory system is called the cardiac output.
Stroke volume is the amount of blood that pushed out of the ventricle in one contraction or one beat.

Thus, cardiac output = Heart rate × Stroke volume. The value of cardiac output is expressed as litre/minute.
