Gastrointestinal System
Your gastrointestinal system is your stomach, large intestine and small intestine. `Gastro' means stomach, so gastro + intestinal = stomach and intestines.
Your gastrointestinal system processes the food that you eat, taking nutrients from it, and then getting rid of the waste that your body doesn't need.
