Lymphoid nodules in the wall of the intestine that form part of the enteric immune system.
Any of numerous large oval patches of closely aggregated nodules of lymphoid tissue in the walls of the small intestines esp. in the ileum that partially or entirely disappear in advanced life and in typhoid fever become the seat of ulcers which may perforate the intestines --called also Peyer's gland Peyer, Johann Conrad (1653-1712), Swiss physician and anatomist.
aggregated lymph nodules that are most abundant in the ileum; also called aggregated lymphatic follicles
Nodules of lymphoid tissues located in the submucosa (under the surface mucosal membrane) of the small intestine. They typically contain B cells, plasma cells and germinal centers.

Peyer's patches are whitish glands of lymphatic follicles in mucous and submucous layers of the small intestine (especially throughout the lining of the ileum along the right side of the abdomen). Edgar Cayce sometimes spoke of these lymphatic tissues with regard to the functioning of the lacteal ducts and coordination of the nervous system.
ovoid, elevated patches of closely packed lymphoid follicles in the mucosa and submucosa of the small intestine. Also called aggregated lymphoid follicles.

Lymphoid nodules seen in the lamina propria of the large intestine and appendix
Collections of lymphoid cells in the wall of the gut which form a secondary lymphoid tissue.
Peyer's patches are secondary lymphoid organs named after the 17th-century Swiss anatomist Hans Conrad Peyer. They are aggregations of lymphoid tissue that are usually found in the lowest portion of the small intestine (ileum) in humans; as such, they differentiate the ileum from the duodenum and jejunum in that the number of peyer's patches increase further down the intestine (ie. terminal iliem contains most peyer's Patches).
