Gut-associated immune system

from Wikipedia, the free encyclopedia

The gut-associated lymphatic tissue (gut-associated immune system) or GALT (from English gut associated lymphoid tissue ) is the part of the lymphatic system in the area of ​​the intestine . Due to its large surface, the intestinal mucosa is of particular importance for the immune system . 70–80% of all cells that produce antibodies are found in the lining of the intestine.

Diffuse accumulations of lymphocytes or loose associations of these ( lymph follicles ) can be found in the entire gastrointestinal tract , which comes into contact with germs and foreign bodies particularly often through the food ingested. In the ileum (ileum) and the appendix ( vermiform appendix ) organized lymphoid tissue exists in the form of the Peyer's patches .
