Note we define this generically to include invertebrates (partly for consistency with GO), but the class may be split in future. We may explicitly make this a developmental class
In humans: originates from the foregut at the opening of the bile duct into the duodenum and continues through the small intestine and much of the large intestine until the transition to the hindgut about two-thirds of the way through the transverse colon

Middle subdivision of a digestive tract[CJM]. In vertebrates: The middle part of the alimentary canal from the stomach, or entrance of the bile duct, to, or including, the large intestine[GO].

The bilaterian gut is typically a complete tube that opens to the exterior at both ends. It consists of mouth, foregut, midgut, hindgut, and anus (reference 1); Although all vertebrates have a digestive tract and accessory glands, various parts of this system are not necessarily homologous, analogous, or even present in all species. Therefore, broad comparisons can be best made under the listings of headgut, foregut, midgut, pancreas and biliary system, hindgut (reference 2).[well established][VHOG]
