When a liver is working well, it cleans the blood, helps digest food and fights infection. It is also a bit of a bodily superhero — much like Wolverine and Deadpool, it has the power to regenerate when it has been damaged, replacing old tissue with new cells.
“Anything that keeps your liver from doing its job — or from growing back after injury — may put your life in danger,” the American Liver Foundation warns. That can be inflammation, scarring, cancer or even using too much Tylenol. Although the liver lies on the inside of the body, the body shows outward signs when something is wrong.
