5. B Cell----------T Cell B cells B cells produced in the stem cells of the bone marrow; they produce antibody and oversee humoral immunity produced in the stem cells of the bone marrow; they produce antibody and oversee humoral immunity T cells T cells non-antibody-producing lymphocytes which are also produced in the bone marrow but sensitized in the thymus and constitute the basis of cell-mediated immunity. non-antibody-producing lymphocytes which are also produced in the bone marrow but sensitized in the thymus and constitute the basis of cell-mediated immunity.

6. White Blood Cell Role in fighting attacking antigens Phagocytes Ingest microbes, other cells and foreign particles Killer T-cell Kill the body’s own cells that between invaded by the viruses or bacteria. Prevents the bug from reproducing. Helper T-cell Stimulate the b cells to make antibodies, and help killer cells develop. Supressor T-cell Emerge from the wilderness bearing surface maker. B-cell React against invading bacteria or viruses by taking proteins called antibodies.
