gastrointestinal system

The gastrointestinal (GI) system is a series of organs that work together to digest food, absorb nutrients, and eliminate waste. It starts with the mouth, where food is chewed and mixed with saliva. It then moves through the esophagus to the stomach, which breaks down food further. The small intestine absorbs nutrients into the bloodstream, while the large intestine absorbs water and forms waste. The process concludes with the rectum and anus, where waste is expelled. Overall, the GI system is essential for turning food into energy and nutrients your body needs to function.
