General Information
Term gut epithelium ID (Ontology) FBbt:00047166 (Fly Anatomy)
Definition A tubular epithelium composed of a monolayer of cells. Different regions have different developmental origins. Both the foregut and hindgut originate from the ectoderm, whereas the midgut originates from the endoderm. A layer of cuticle lines the foregut and hindgut. In the midgut, a semipermeable chitinous layer, the peritrophic matrix, protects the epithelium from physical damage and regulates the passage of particles between the lumen and enterocytes.[ FlyBase:FBrf0222424 ]
