An individual blood cell takes about 60 seconds to make a complete circuit of the body

Interesting Fact About Our Blood. 

You have about 5 liters of blood in your body (at least, most people do) and the average heart pumps about 70 mL of blood out with each beat. A healthy heart also beats around 70 times a minute. So, if you multiply the amount of blood that the heart can pump by the number of beats in a minute, you actually get about 4.9 liters of blood pumped per minute, which is almost your whole body’s worth of blood. In just a minute, the heart pumps the entire blood volume around your body.
