GENERAL HISTOLOGY

Detailed explanation-1: -Peyer’s patches are located in your small intestine, usually in the ileum area. The ileum is the last portion of your small intestine. In addition to further digesting the food you eat, the ileum also absorbs water and nutrients from food.

Detailed explanation-2: -The gut-associated lymphoid tissue (GALT) consists of isolated or aggregated lymphoid follicles forming Peyer’s patches (PPs). By their ability to transport luminal antigens and bacteria, PPs can be considered as the immune sensors of the intestine.

Detailed explanation-3: -Conclusion: Peyer’s patches are concentrated in the distal 25 cm of ileum but extend proximally for 200 cm. The variation in their size, shape, and distribution in different individuals is greater than often appreciated and may influence the presentation of diseases centered on these structures.

Detailed explanation-4: -Peyer’s patches are found in the submucosa of the distal end of the small intestine. The myenteric nerve plexus provides the major nerve supply to the GI tract wall and controls GI motility. The first teeth to appear are the deciduous teeth. Dentin anchors the tooth in place.
