Appendix

It is easy to see in this picture the lymphatic rings of the mucosa (purple) extending into the submucosa (green). Because of this nodules the lumen is very small. Crypts are short for the appendix does very little absorption or indeed secretion.

Differential diagnosis: Small luminal organs can be easily confused with the appendix, for example ureter, fallopian tube and vas deferens. The vas and ureter have very thick muscular coats, with very little mucosa or lumen. Fallopian tube can be distinguished by its numerous branching mucosal folds. Appendix has several lymphatic rings which are diagnostic.
