===Ileum===
===Ileum===
*Peyer's Patches
*''Peyer's Patches'', part of the mucosal associated lymphoid tissue (MALT), are present throughout the ileum and ileocaecal junction.
**They contain B and T lymphocytes.
**B lymphocytes exist in follicles.
**M cells are present in the overlying epithelium. M cells transfer soluble antigen from the intestinal lumen to the underlying lymphocytes.
**Some enterocytes in this area are involved in the transport of soluble antigen, and therefore have no digestive function.
