hindgut http://upload.wikimedia.org/wikipedia/commons/f/f7/Gray472.png SCTID:362856002 BILA:0000087 in FMA this class has no children. In MA it has a single child hindgut epithelium XAO:0000104 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] Wikipedia:Hindgut Note we define this generically to include invertebrates (partly for consistency with GO), but the class may be split in future (vertebrates have some contribution from NC - https://github.com/obophenotype/uberon/wiki/The-neural-crest).
