Liver

Your liver is one of the biggest and busiest organ in your body. It has hundreds of different jobs to do.

For example, it makes a nasty substance called bile, which is important because it helps to break the food down in your body. It also helps to work out what your body needs from food - the nutrients - and if you've got too much of something, it can store it up!
