Cardiac output is determined by the product of stroke volume and heart rate. At rest, stroke volume is about 70 mL and heart rate is 72 beats per minute. Thus, the cardiac output is 72 × 70 or 5040 mL i.e., about 5.5 litres blood per minute is pumped by the human heart.

Cardiac output is determined by the product of stroke volume and heart rate. At rest, stroke volume is about $70 m L$ and heart rate is 72 beats per minute. Thus, the cardiac output is $72 \times 70$ or $5040 m L$ i.e., about $5.5$ litres blood per minute is pumped by the human heart.
