Gastrointestinal tract

Dr Daniel J Bell and Dr Henry Knipe et al.

The gastrointestinal tract (GI tract) includes any part of the oral cavity, oropharynx, hypopharynxesophagus, stomach, small bowel, colon, rectum and anal canal


The non-qualified term bowel , a.k.a. intestines or gut, is used to refer to the combination of the small bowel and large bowel. It therefore encompasses the GI tract from the start of the duodenum (gastroduodenal junction) to the anus
