APPLIED RADIOLOGICAL ANATOMY

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: -Peyer’s patches are small masses of lymphatic tissue found throughout the ileum region of the small intestine. Also known as aggregated lymphoid nodules, they form an important part of the immune system by monitoring intestinal bacteria populations and preventing the growth of pathogenic bacteria in the intestines.

Detailed explanation-3: -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-4: -These patches are small masses of lymphatic tissues found all through the ileum area (last portion of the small intestine) of the small intestine. Apart from digesting the food you eat further, the ileum also absorbs nutrients and water from food.
