Study Notes
- Lymphoid organs include the spleen, thymus gland, tonsils, Peyer's patches, and scattered lymphatic tissue.
- Lymphoid organs are characterized by predominance of reticular connective tissue and lymphocytes.
- Only lymph nodes filter lymph.
- The spleen is the largest lymphoid organ and filters and cleanses blood, destroys worn-out red blood cells, and stores platelets.
- The thymus gland produces thymosin that develops active T-lymphocytes.
- MALT (mucosa-associated lymphoid tissue) contains B and T-lymphocytes and is involved in early detection of invaders.
- Tonsils are small masses of lymphatic tissue that surround the pharynx and function to trap and remove pathogens.
- Peyer's patches are located in the wall of the small intestine and contain macrophages to capture and destroy bacteria.
- The body has two defence systems to fight foreign pathogens: nonspecific and specific.
- The nonspecific defence system includes the skin, mucous membranes, phagocytic white cells, anti-microbial proteins, and inflammatory response and fever, while the specific defence system includes lymphocytes and antibodies.
