Information:
In our bodies there is approximately 4.7- 5.5
litres of blood (for an average adult), a child
who is of average build and weighs 80

litres of blood.
For an average sized human of an average
weight and health, and resting heart rate. It
would take around about 1 minute for their

blood has to travel the same distance
though. Generally blood travels at around 3
feet per second.
Factors that can affect the above calculation
can be: their height, weight, body
proportions, type of exercise and blood
pressure. So each individual is different.
