What does the liver do?

Bile, a digestive fluid that breaks down fats
Proteins that help your blood clot
Cholesterol, which your body needs to make certain hormones
Other things the liver does include:
Storing sugar to release when your body suddenly needs extra energy
Breaking down drugs, poisons, and other substances so your body can get rid of them
