If bruises and blood blisters are bleeding beneath the skin, when it heals that blood has to have gone somewhere right?
In: Biology
It’s cleared out by various white blood cells. Ultimately, the breakdown products of red blood cells – particularly hemoglobin – are processed by the liver. This produces a chemical called *bilirubin*, which is a major component of bile; that bile is duped into your intestines and you poop it out. It’s why poop and bruises have the same colors (pale yellow to brown and black), actually – both get their color from bilirubin and its breakdown products.
