    that cause disease (antigens). The cells in the system are leukocytes (white blood cells) called phagocytes and lymphocytes. Phagocytes are the first line of defence‚ providing a general barrier against antigens. Leukocytes are more focused and are a second line of defence against specific antigens. T-lymphocytes (T-cells) attack anything carrying disease in the body. B-lymphocytes (B-cells) are tuned to a particular antigen‚ and produce antibodies to destroy them. Immunosuppression is a reduction
