"Me," Tae answered with a roll of her eyes. "I know what livers do. Medical science knows what livers do. And it's important. Basically all organs do."

She sighs. Apparently she's going to explain this.

"All the blood that leaves your stomach and intestines is filtered through the liver. It processes out toxins in the body, like drugs and alcohol. It is also responsible for producing bile, which helps us to digest fats as well as carry away waste in the body. And that's just a few of the things it does, not even remotely all of it. You need your liver, and even if it is one of the more self-regenerative organs, it's vital."
