what is the largest of the lymphoid tissue found in the pharynx?
lymphangion
there are three types of situations in which malt is present- tonsils, appendix, small intestinal area





























malt constitute about 50% of the lymphoid tissue in human body.





























section::::categorization.





























the components of malt are sometimes subdivided into the following:





























bullet::::- galt (gut-associated lymphoid tissue. peyer's patches are a component of galt found in the lining of the small intestines.)





























bullet::::- balt (bronchus-associated lymphoid tissue)





























bullet::::- nalt (nasal-associated lymphoid tissue)





























bullet::::- calt (conjunctival-associated lymphoid tissue)





























bullet::::- lalt (larynx-associated lymphoid tissue)





























bullet::::- salt (skin-associated lymphoid tissue)





























bullet::::- valt (vulvo-vaginal-associated lymphoid tissue)





























it can be also distinguished by level of organization of the tissue:
mucosa-associated lymphoid tissue
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, oral passage, nasopharyngeal tract, thyroid, breast, lung, salivary glands, eye, and skin. malt is populated by lymphocytes such as t cells and b cells, as well as plasma cells and macrophages, each of which is well situated to encounter antigens passing through the mucosal epithelium. in the case of intestinal malt, m cells are also present, which sample antigen from the lumen and deliver it to the lymphoid tissue.
