What is the primary function of lymphocytes in the immune system?

Lymphocytes are a type of white blood cell that play a crucial role in the immune system, primarily responsible for the production of antibodies. These antibodies are essential components of the immune response, functioning to identify and neutralize pathogens such as bacteria and viruses. When lymphocytes are activated by exposure to specific antigens, they differentiate into plasma cells that secrete antibodies. These antibodies specifically target the pathogens, helping to clear infections and providing long-term immunity against future exposures to the same antigens. The ability of lymphocytes to recognize and remember specific pathogens is fundamental to both the adaptive immune response and the body's capacity to respond effectively to subsequent infections.
