gastrointestinal tract?</h3>
The digestive system's path from the mouth to the anus is known as the gastrointestinal tract (GI tract, digestive tract, alimentary canal). All of the major digestive system organs, such as the esophagus, stomach, and intestines, are located within the GI tract in both humans and other animals. Food that is consumed by mouth is broken down into nutrients and energy, and the leftover waste is ejected as feces at the anus. An adjective describing the stomach and intestines is "gastrointestinal."
