1 The white blood cells produce an antibody specific to that antigen. 2  This is called sensitization.. 3  The job of the antibodies is to help white blood cells detect and destroy substances that cause disease and sickness.llergic Reaction Causes. Almost anything can trigger an allergic reaction. 1  The body's immune system involves the white blood cells, which produce antibodies. 2  When the body is exposed to an antigen (a foreign body such as pollen that can trigger an immune response), a complex set of reactions begins.
23. Distinguish between antigen and antibody. Antigens are substances that provoke an immune response (they're the ultimate target for the immune system). Antibodies are simply proteins that are secreted as a result of the antigen provoked immune response. In short, antigens cause the disease and antibodies cure it.24.ntigens are substances that provoke an immune response (they're the ultimate target for the immune system).
