Question

why do you think that the intestines have one of the body's most well-developed sets of lymphoid tissues?

Answer 1

The gut-associated lymphoid tissue lies throughout the intestine, covering an area of approximately 260–300 m². The GALT (gut associated lymphoid tissue) includes the Peyer's patches of the small intestine, there the isolated lymphoid follicles prevalent throughout the intestine. Lymphoid tissue in the gut includes Waldeyer's tonsillar ring, Peyer's patches, lymphoid aggregates in the large intestine. This (intestine) possesses the largest collection of lymphoid tissue in the human body. The GALT is composed of several types of lymphoid tissue that are responsible to store immune cells including T and B lymphocytes. They are able to carry out attacks and defend against pathogens.
