<unk> s, also called<unk> sma B<unk> s, are white blood<unk> s that originate in the lymphoid organs as B lymphocytes and secrete large quantities of proteins called antibodies in response to being presented specific substances called antigens. These antibodies are transported from the<unk> s by the blood<unk> sma and the lymphatic system to the site of the target antigen (foreign substance), where they initiate its neutralization or destruction. B<unk> s differentiate into<unk> s that produce antibody molecules closely modeled after the receptors of the precursor B<unk> .
