Digestive System
The food you swallow goes on a long journey through your body. The digestion process begins as you take
your first bite of food and ends as your body disposes of the unusable parts. The digestive system mixes,
mashes, and breaks down foods into nutrients that your body can use. What is not needed leaves your body.
