The "B" in B cells stands for "bone marrow," as these cells were originally identified in birds' bursa of Fabricius, an organ involved in their immune response. B cells are a type of lymphocyte crucial for the adaptive immune system, primarily responsible for producing antibodies to fight infections. They play a key role in humoral immunity, distinguishing them from T cells, which mature in the thymus.
