APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Production of secretory IgA occurs and other immune cells then enter systemically through the Peyer’s patches and into the mesenteric lymph system. IgA cells prevent pathogens from adhering to the intestinal surface thus preventing gut cell damage.

Detailed explanation-2: -However, Peyer’s patches keep the intestinal flora at appropriate levels and the pathogens at bay, thereby preventing a large number of infections. As a part of the pathogenesis of food allergy, the Peyer’s patches and vasculature of lamina propria allow the circulation of inflammatory cells to the immune structures.

Detailed explanation-3: -Peyer’s patches are groupings of lymphoid follicles in the mucus membrane that lines your small intestine. Lymphoid follicles are small organs in your lymphatic system that are similar to lymph nodes.

Detailed explanation-4: -Peyer’s patches (about 8–10) and SF are found in the walls of the small intestine or both small and large intestine, respectively.
