Duodenum: The duodenum has three layers, which are similar to all hollow organs of the GIT, but it also has Brunner’s glands, which are the duodenum’s distinguishing feature. It is the first of the three segments of the small intestine, receiving partly digested food from the stomach and beginning nutrient uptake. It is directly connected to the stomach’s pylorus.-
Esophagus: A stratified squamous epithelium lines the esophagus for protection. It is non-keratinized since it is rarely exposed to dehydration or abrasions. Lubrication is provided by scattered submucosal mucous glands. The peristalsis of passed food is provided by a well-developed muscularis.
-
Appendix: The appendix has the same structure as the large bowel: serous, muscular, submucous, and mucous. The lamina propria of the appendix contains extensive clumps of lymphoid tissue that protrude into the lumen. These collections are most noticeable in childhood and gradually fade with adulthood. Columnar epithelium lines the appendix mucosa, which contains a considerable number of endocrine cells as well as goblet cells.
