Question

Cardiac output is blood

• A. Received by heart per minute
• B. Pumped by ventricles per sec
• C. Pumped by each ventricle per minute
• D. Pumped by left ventricle per hour

Answer 1

Answer: (C)

Pumped by each ventricle per minute

Cardiac output is defined as the volume of blood pumped by left ventricle into the aorta per minute.

It is calculated as:

Cardiac output = Stroke volume (SV) x Heart rate (HR)

= 70 mL x 75

= 5250 mL/ min or 5.25 L/min

where, stroke volume is the amount of blood supplied to heart by the veins.

So, the correct answer is 'Pumped by each ventricle per minute'.
