Lymphoid Tissue is organized as the primary lymphoid organs including thymus and bone marrow. secondary lymphoid organs includes spleen, tonsils, lymph vessels, lymph nodes, adenoids, skin, and liver. And lymph fluid (The fluid which lies in the interstices of all body tissues). MALT (mucosa-associated lymphatic tissue) is a diffuse system of small concentrations of lymphoid tissue found in various sub-mucosa membrane sites of the body, such as the gastrointestinal tract, thyroid, breast, lung, salivary glands, eye, and skin. which is subdivided into GALT and BALT. GALT (Gut-associated lymphoid tissue or Gut-Associated Lymphatic Tissue) it works to protect the body from invasion. BALT (Bronchus-associated lymphoid tissue) is a constitutive mucosal lymphoid tissue aggregations of B and T lymphocytes in the lower respiratory tract.
