claimLymphoid organs are categorized into central (primary) lymphoid organs, where lymphocytes are generated, and peripheral (secondary) lymphoid organs, where adaptive immune responses are initiated and lymphocytes are maintained.
claimAntigen is carried from sites of infection to peripheral lymphoid organs primarily within macrophages and dendritic cells.
claimAfter completing maturation, both B and T lymphocytes enter the bloodstream and migrate to the peripheral lymphoid organs.
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.

claimPeripheral lymphoid organs are specialized to trap antigen, allow the initiation of adaptive immune responses, and provide signals that sustain recirculating lymphocytes.
claimThe peripheral lymphoid organs, which include the lymph nodes, the spleen, and the mucosal lymphoid tissues, are the sites where antigen and lymphocytes encounter each other.
claimLymphoid organs are categorized into central (primary) lymphoid organs, where lymphocytes are generated, and peripheral (secondary) lymphoid organs, where adaptive immune responses are initiated and lymphocytes are maintained.
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).
claimMature lymphocytes continually recirculate from the bloodstream through peripheral or secondary lymphoid organs and return to the bloodstream via lymphatic vessels.
