Adaptive (specific) defense system is the third line of defense. It mounts attack against particular foreign substances, takes longer to react than the innate system, works in conjunction with the innate system. The adaptive immune system is antigen-specific, systemic, and has memory. It has two separate but overlapping arms: Humoral, or antibody-mediated (B Cell) immunity and Cellular, or cell-mediated (T Cell) immunity. In the first exposure to antigen, Activated B lymphocytes will give rise to plasma cell which in turn produce antibodies against the antigen by cloning. Activated helper T cell has a central role in adaptive immune response, it activates the B lymphocyte and the cytotoxic T cell for immune response
