Lymphocytes are specialized white extraction cells whose function is to identify and destroy invading antigens. Some lymphocytes senesce in the bone marrow and are called B lymphocytes or B cells.

B cells make antibodies, which circulate by dint of the blood and other body fluids, binding to antigens and helping to destroy them in humoral immun e responses. Another type of lymphocyte, cal! led T lymphocytes or T cells, mature in the thymus, a tenuous gland located behind the breastbone. Some T cells, called slayer giant T cells, generate cell-mediated immune responses, directly destroying cells that have unique(predicate) antigens on their surface that are recognized by the sea wolf T cells.
