How long before blood comes back to the heart?

It takes blood about one minute to make one complete circuit

throughout your body. But this is only for the major arteries and

veins. The average person has enough blood vessels, if you include

all the venules, arterioles, and capillaries, to go around the

world twice. So, then it would take much longer if included them

too!
