MICROANATOMY

Detailed explanation-1: -Peyer’s patches (PPs) are a series of small lymphoid organs situated in the wall of the small intestine.

Detailed explanation-2: -GALT is present throughout the GI tract in mammals as aggregated and solitary lymphoid nodules, known as Peyer’s patches [3, 4]. However, the appearance, number and organization of lymphoid follicles differ within small intestine, i.e., between jejunum and ileum.

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.
