The primary function of humoral immunity is to produce antibodies that circulate in body fluids, such as blood and lymph, to neutralize or eliminate pathogens, such as bacteria and viruses, before they can infect cells. Humoral immunity is part of the adaptive immune response and is carried out by B lymphocytes (B cells).
