    T cells mature and become immunocompetent in the thymus.
  • What is the role of secondary lymphoid organs?
    Secondary lymphoid organs are where T and B cells first encounter antigens and actively participate in immune responses.
  • What are MALT and where are they found?
    MALT, or mucosal-associated lymphoid tissues, include tonsils and Peyer's patches, found in the head and digestive system respectively.
