Where are aggregated lymphoid nodules?

ileum
Aggregated lymphoid nodules are an important part of the gut-associated lymphoid tissue (GALT). They are mainly distributed in the ileum and appendix of animals and humans but their distribution in the cardiac glandular area has not been reported.

Which lymphoid organs are lymphoid nodules present?

Primary lymphoid organs include the thymus, bone marrow, fetal liver, and, in birds, a structure called the bursa of Fabricius.

In which region the lymphatic nodules are known as malt?

The mucosa-associated lymphoid tissue (MALT), also called mucosa-associated lymphatic tissue, is a diffuse system of small concentrations of lymphoid tissue found in various submucosal membrane sites of the body, such as the gastrointestinal tract, nasopharynx, thyroid, breast, lung, salivary glands, eye, and skin.

What is the lymphoid nodules located in the wall of the ileum?

Aggregates of lymphoid nodules located in the wall of the ileum are: Peyer’s patches. Peyer’s patches prevent bacteria from migrating through the wall of the intestine.

What is aggregate nodule?

What are lymphoid aggregates?

Lymphoid aggregate/infiltrate: A collection of B cells, T cells, and supporting cells, present within the stroma of various organs. The term can be used to describe endogenous lymphoid tissue or acquired lymphoid tissue.

Where is MALT tissue located?

Mucosa-associated lymphoid tissue (MALT) is a network of lymphoid cell aggregates and tissue that is distributed in submucosal layers of the gastrointestinal, genital, respiratory, and urinary tracts, as well as in the eyes, skin, thyroid, breasts, tonsils, and salivary glands.

What are aggregated lymphatic follicles?

ag·gre·gat·ed lymphatic follicles n. Collections of many lymphoid follicles closely packed together, forming oblong elevations on the mucous membrane of the small intestine. Also called aggregate glands, agminate glands, Peyer’s patches.

Are the aggregates of lymphoid nodules located in the wall of the ileum of the small intestine?

Peyer’s patches are small masses of lymphoid tissue found throughout the wall of the ileum region of the small intestine of mammals. It is also known as lymphoid nodules. It is an important part of the immune system which prevents the growth of antigen like pathogenic bacteria in the intestines.
