Question

Which of the following will be the cardiac output of the heart that has stroke volume of $75$ mL and is beating at the rate of $80$ per minutes?

• A. $6$ L/min
• B. $6.25$ L/min
• C. $5.25$ L/min
• D. $60$ L/min

Answer 1

The correct option is A $6$ L/min

Cardiac output = stroke volume× heart rate

Stroke volume=75ml

Heart rate = 80/min

Putting these values in the above formula we get,

CV=0.75 L×80per minute

=6L/min
