editor note
  • TODO - abstract this such that it legitimately covers all vertebrates
  • Some references do not consider the caecum to be part of the colon.

homology notes
  • 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.[uncertain][VHOG]
