The gastrointestinal tract, often called the GI tract, is a long tube that runs from the mouth to the anus. It includes organs such as the esophagus, stomach, small intestine, large intestine, and rectum. This system is essential for breaking down food so that the body can absorb nutrients and eliminate waste. It plays a key role in digestion and overall health.
