Your liver is a key player in your body's digestive system. Everything you eat or drink, including medicine, passes through it. You need to treat it right so it can stay healthy and do its job. It's an organ you could easily damage if you don't take good care of it. Your liver has several important things to do. It helps clean your blood by getting rid of harmful chemicals that your body makes. It makes a liquid called bile, which helps you break down fat from food. And it also stores sugar called glucose, which gives you a quick energy boost when you need it.
