We may explicitly make this a developmental class TGMA:0001020 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] The caudalmost subdivision of a digestive tract. UBERON:0001046 UMLS:C0231053 VHOG:0000459 XAO:0000104 in FMA this class has no children. In MA it has a single child hindgut epithelium metenteron the caudal portion of the primitive digestive tube of the embryo uberon mesenchyme subdivision of digestive tract
