Understand that Peyer's patches are small masses of lymphatic tissue found in the small intestine, particularly in the ileum.
Recognize that the primary function of Peyer's patches is related to the immune system, specifically in the gut.
Identify that Peyer's patches play a crucial role in monitoring intestinal bacteria and preventing the growth of pathogenic bacteria.
Note that Peyer's patches contain immune cells such as B cells, T cells, and macrophages, which help in detecting and responding to pathogens.
