The longest tube in the body is the gastrointestinal (GI) tract, specifically the small intestine, which can measure about 20 feet (6 meters) in length in adults. It plays a crucial role in digestion and nutrient absorption. The small intestine is divided into three sections: the duodenum, jejunum, and ileum. Overall, the entire GI tract, including the esophagus and large intestine, forms an extensive tubular system.
