From ventricle to ventricle, there are more than 50 miles worth of capillaries in which the heart pumps blood around the body.(edt) The various sources I consulted were rather vague on the subject, but I've seen estimates around 60,000 miles (or 100,000 km) in children, and 100,000 miles (161,000 km) in adults for the total length of blood vessels in general. True, this includes arteries and veins also, but most of that length would still be capillaries. Therefore it should be way more than 50 miles...
About 1,506 miles (or as an extra fact, 2,424 kilometers)
