Antibodies
Chloro-Fluoro-Carbons (CFC's)
Antibodies attach to antigens preventing them from attacking cells in the body. Antitoxins attack antigens and destroy them
Cell-mediated immunity
Lymphocytes that act directly on antigens to destroy them or produce chemicals that are toxic to them are called T4 cells. They are also known as T helper cells.

Antigen is a substance that can induce the generation of antibodies, any substance that can induce immune response. Antibody is a protective protein produced by the body in response to an antigen.
The antigen itself cannot destroy the pathogen but here are three ways it helps out:1. Antibodies can clump antigens together in order to enhance phagocytosis2. Antibodies can activate the cytotoxic cell responses (a chemical that destroys antibody-bound antigen).3. Antibodies can activate B lymphocytes, which results in the production on plasma and memory cells.
plasma cells
Killer T cells (CTLs) use lymphotoxin to destroy antigens.
The humans destroy ozone by usng CFCs. These are compounds which react with ozone to deplete it.
The immune system protects the body from free antigens. It does so through the production of antibodies that recognize and neutralize antigens, as well as through the activation of immune cells, such as T cells and natural killer cells, that can directly destroy cells infected with antigens. Additionally, the immune system has memory cells that can recognize and respond more quickly if the same antigen is encountered again in the future.
