Module 4: Immunity

What is the function of antibodies within the immune system?

• Antibodies kill off any antigen that enters the body.

• Antibodies are only made when you are given a vaccination for specific antigens.

• Antibodies bind to specific antigens to flag for destruction.

• Antibodies are part of an external defense mechanism.

What happens after the second time you are exposed to a pathogen?

• The body will not be able to fight off the pathogen quickly, because it knows how to get into the body easier.

• The body's immune system will react the same was as it did during the first exposure.

• The body can only be exposed to a pathogen a second time if you do not have a vaccine.

• The body will know how to fight off the pathogen quickly, because memory cells have been created after the first encounter.
