Our body is many things: a mechanical device, a walking chemistry set, a sustainable life form, and an ever-changing biological phenomenon. There’s a lot to know about the body. Were you aware of these ten amazing facts?
For every pound of fat gained, we add seven miles of new blood vessels.
New tissue needs blood supply, so our vascular system expands to accommodate it. This also means our heart must work harder to pump blood through the new network, which may reduce oxygenation and nutrient replenishment in other tissues. Lose a pound? Our body will break down and reabsorb the unneeded blood vessels from the previous tissue.
