Term information

database cross reference


  • The part of the digestive system that excludes the hepatobiliary system.
editor note
  • the decision to split digestive and gastrointestinal in this way may be revisited. As it currently stands, this class more closely aligns what MA calls the alimentary system
external definition
  • The system that includes the esophagus, stomach, small and large intestine, anus, liver, biliary tract, and pancreas[ncithesaurus:Gastrointestinal_System].
external ontology notes
  • that many anatomy ontologies consider this synonymous with digestive system. here we follow MA in dividing digestive system into gastrointestinal and hepatobiliary. hepatobiliary includes the liver and biliary tract. species-specific AO classes are categorized according to whether liver is included. For example, XAO includes liver as part of XAO:0000125 alimentary system, so we assume this class is the more generic class. We have one entity that is part of both gastrointestinal and hepatobiliary systems: hepatopancreatic ampulla.
