Example of 1st line of defense mechanism.

• Skin

• Fever

• Antibodies

• Inflammation

Sweat and skin secretions contain a mixture of molecules that kills or limits the growth of many types of microbes. This control of microbes is an example of which of the following?

• a nonspecific defense against infection

• an enzyme-catalyzed biochemical reaction.

• a feedback loop to maintain homeostasis.

• a specific immune response to infection by microbes.

How is the use of a vaccine stimulate the immune system to act against a specific pathogen, useful in maintaining homeostasis ?

• The body can now digest the weakened microbes and use them as food.

• The vaccine provides more stress to the immune system and the more the immune system is challenged, the better it performs.

• The body will produce antigen specific antibodies in order to respond quickly to the particular pathogen. 

• Once the body produces antibodies to combat one type of virus, it can combat any other virus that invades the body.
