claimThe adaptive immune system functions to address pathogens that bypass the non-specific protection mechanisms of the innate immune system.
claimThe primary purpose of dendritic cells is to bridge the innate and adaptive immune responses.
claimNatural killer (NK) cells prevent viral infections from becoming too severe while the adaptive immune system generates a targeted response.
claimFollowing a second exposure to a pathogen, some individuals may experience less severe symptoms and a shorter duration of illness due to the adaptive immune system's response.
claimT cells and B cells are the two primary cell types central to the adaptive immune response.
claimFollowing a second exposure to a pathogen, some individuals may experience no symptoms and may not realize they were exposed due to the adaptive immune system's response.
claimThe adaptive immune system functions to stop current infections and generate immunologic memory.
claimB cells are an essential part of the adaptive immune response and can serve as antigen-presenting cells (APCs) to activate responses against toxins or smaller antigens like proteins.
claimSecondary immune responses are immunologic responses driven by memory cells that allow the adaptive immune system to produce a faster and more efficient response to subsequent attacks.

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.
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.
claimAdaptive immune responses are typically triggered when a recirculating T cell recognizes its specific antigen on the surface of a dendritic cell.
referenceA pluripotent hematopoietic stem cell gives rise to lymphocytes responsible for adaptive immunity, as well as myeloid lineages that participate in both innate and adaptive immunity.
claimPeripheral lymphoid organs are specialized to trap antigen, allow the initiation of adaptive immune responses, and provide signals that sustain recirculating lymphocytes.
claimAdaptive immune responses are initiated in peripheral lymphoid tissues, where T cells that encounter antigen proliferate and differentiate into antigen-specific effector cells, and B cells proliferate and differentiate into antibody-secreting cells.
claimLymphoid organs are organized tissues containing large numbers of lymphocytes within a framework of nonlymphoid cells, where interactions between these cell types support lymphocyte development, the initiation of adaptive immune responses, or lymphocyte sustenance.
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.
referencePeripheral lymphoid tissues operate by trapping antigens from sites of infection and presenting them to migratory small lymphocytes to induce adaptive immune responses.
