A type of white blood cell involved in the specific immune response; some lymphocytes produce antibodies.
Revise: Immune System and DefencesLymphocytes are white blood cells involved in the specific immune response. Exposure to a pathogen’s antigens triggers suitable lymphocytes to multiply and produce antibodies. This takes time during a first infection, so the pathogen may multiply and cause symptoms before the response brings it under control.
A white blood cell that produces antibodies to help destroy pathogens and antitoxins to neutralise their toxins.
Distinguish the antigen on a pathogen from the antibody produced by a lymphocyte. Their shapes are complementary.
Explain a secondary response by linking memory lymphocytes to faster production of larger quantities of specific antibodies.
