gastrointestinal tract
The gastrointestinal tract, often called the digestive tract, is a series of hollow organs that process food. It starts at the mouth, where food is chewed and mixed with saliva, then moves through the esophagus to the stomach. In the stomach, food is broken down further. It then passes into the small intestine, where nutrients are absorbed. The leftover waste goes into the large intestine, where water is reabsorbed and solid waste is formed. Finally, waste is expelled from the body through the rectum. This process is essential for converting food into energy and nutrients needed for health.

The gastrointestinal (GI) tract is a series of hollow organs that work together to digest food. It starts at the mouth, where food is chewed and mixed with saliva, and continues through the esophagus, stomach, and intestines, ending at the rectum. Along this pathway, food is broken down into nutrients that the body absorbs for energy, growth, and repair. The GI tract also produces digestive juices and houses beneficial bacteria that aid in digestion. Proper function of this system is essential for overall health, as it plays a key role in nutrition and immune function.
