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] UBERON:0001555 UMLS:C0017189 VHOG:0000309 WBbt:0005743 ZFA:0000112 alimentary canal alimentary tract digestive canal digestive tube enteric tract galen:AlimentaryTract gut gut tube uberon we following Kardong in naming the entire tube from mouth to anus the alimentary canal.
