claimPeripheral lymphoid organs, which include the lymph nodes, the spleen, and the mucosal lymphoid tissues, are specialized to trap antigen, initiate adaptive immune responses, and provide signals that sustain recirculating lymphocytes.
claimLymph nodes, the spleen, and mucosal-associated lymphoid tissues share the same basic architecture.
claimThe spleen is composed of red pulp, which serves as the site of red blood cell disposal, and white pulp, which consists of lymphocytes surrounding arterioles.
claimThe spleen is a fist-sized organ located behind the stomach that collects antigen from the blood and disposes of senescent red blood cells.
claimThe white pulp of the spleen is divided into a periarteriolar lymphoid sheath (PALS) containing mainly T cells, and a flanking B-cell corona.
claimThe three major types of peripheral lymphoid tissue are the spleen (which collects antigens from blood), lymph nodes (which collect antigen from infection sites in tissues), and mucosal-associated lymphoid tissues (MALT) (which collect antigens from epithelial surfaces).
procedureNaive lymphocytes circulate continually from the blood into peripheral lymphoid tissues by squeezing between capillary wall cells, and return to the blood via lymphatic vessels or directly from the spleen.

claimPeople without a spleen are at greater risk of suffering from bacterial infections like meningococcus and pneumococcus and should be up to date on vaccines that protect against these infections.
claimThe spleen is the largest internal organ of the immune system and contains a large number of immune system cells.
measurementApproximately 25 percent of the blood that comes from the heart flows through the spleen on every beat.
claimThe spleen is particularly important in protecting people from bacterial infections such as meningococcus and pneumococcus.
claimOrgans and tissues essential to the immune system include the thymus, bone marrow, lymph nodes, lymph vessels, spleen, and skin.
claimThe spleen filters circulating blood to detect pathogens, which triggers the activation and multiplication of immune system cells to neutralize those pathogens.

claimMature T cells leave the thymus as naïve T cells and populate organs such as the spleen, lymph nodes, bone marrow, and blood, where they may become memory T cells after antigen exposure.
claimMonocytes line the walls of blood vessels in organs like the liver and spleen to capture microorganisms passing through the blood.
claimPlasma cells are the mature form of B cells that produce antibodies and are located in the spleen and lymph nodes.
claimMature B cells are located in the bone marrow, lymph nodes, spleen, some areas of the intestine, and the bloodstream.

claimNatural killer (NK) cells are large granular lymphocytes derived from bone marrow precursors that are found mainly in peripheral circulation (5 to 20 percent of total lymphocytes), spleen, liver, and bone marrow.
claimMarginal zone B (MZ B) cells are a rare non-recirculating subset of mature peripheral B cells located exclusively in the spleen, distinct from the more abundant recirculating follicular B cell subset.
claimInvariant NKT (iNKT) cells are located in internal organs, specifically the thymus, bone marrow, liver, and spleen.

claimThe thymus, spleen, and lymph nodes are organs of the immune system.
claimProtein-energy malnutrition (PEM) compromises the functions of lymphoid tissues, including the spleen and lymph nodes.
claimThe spleen is located in the upper abdomen and functions to make antibodies and remove old and damaged red blood cells.
