Question

The volume of blood pumped out by the two ventricles of human heart per minute is

• A. $5L$
• B. $10L$
• C. $15L$
• D. $20L$

Answer 1

The correct option is A $5L$

The correct answer is A.

Cardiac output is the volume of blood being pumped by the heart in a minute. It is equal to the heart rate multiplied by the stroke volume. So if there are 72 beats per minute, and 72 ml blood is ejected with each beat of the heart, the cardiac output is 5184 ml/ minute. Around 5L.
