General Information
Term midgut ID (Ontology) FBbt:00005383 (Fly Anatomy)
Definition The part of the alimentary canal extending posteriorly from the proventriculus to close to the point where the Malpighian tubes are attached and where the hindgut starts. It is predominantly derived from the endoderm and it is lined by the peritrophic membrane.[ FlyBase:FBrf0064792 FlyBase:FBrf0166419 ]
Also Known As "ventriculus"
