B cells are lymphocytes that form part of the humoral immunity branch of the adaptive immune system. They work by producing the neccessary antibodies and presenting antigens to the T cells via immunoglobulin surface receptors. B cells are produced from the pluripotent precursor cells found in the bone marrow.
B cells are a lymphocyte are a specialist lymphocyte that can perfomr two roles in regards to humoral immunity. Typically they are produced in the bone marrow hence the name "B-cell". Some B cells when they mature can specialise as antibody producing plasma cells. these produce antibodies which can bind to antigens presented on the surface of a pathogen creating holes in the in cell wall of the pathogen causing the cells to die. The other specialsim is memory cells that contain the antigens of previous infection; thus if there is a secondary infection and the pathogen presents the same antigens the memory cells have allowed the body to create and sotre antibodies that are complemetary to the specific antigen therefore the immune response this time is much faster[1].
