Awesome
& Little-Known Facts about the Human Body
Your body is many things: a mechanical

biological phenomenon. There’s a lot to know about the body. Were you aware of these ten amazing facts?
1. For
every pound of fat gained, you add seven miles of new blood vessels.
New tissue needs blood supply, so your vascular system

blood through the new network, which may reduce oxygenation and nutrient
replenishment in other tissues. Lose a pound? Your body will break down and
reabsorb the unneeded blood vessels from the previous tissue.
