Feet are made up of many intricate parts, such as 26 bones, 33 joints, 107 ligaments and 19 muscles, and over time, they can get seriously injured because of the constant wear and tear.
Arteries, along with veins and capillaries, are long enough to go around the world at least twice. Their entire length is over 60,000 miles long and they carry oxygenated blood to our whole body, from head to toe.
