Answer 2

Hi....
If you could stretch out all of a human's blood vessels, they would be about 60,000 miles long. That's enough to go around the world twice. The strongest bone in your body is the femur (thighbone), and it's hollow! The width of your armspan stretched out is the length of your whole body.
