About Antibodies
- Some antibodies can directly damage or destroy a pathogen.
- Some antibodies attach themselves to pathogens to make it easier for phagocytes to engulf and destroy them. They act like tags to tell the phagocytes which cells to attack.
- When an organism is infected lymphocytes produce hundreds of different antibodies until one works.
- Once a lymphocyte has produce a working antibody it will remember and reproduce it any time the same pathogen infects the organism.
