the body and cause

diseases.List and describe the 5 main pathogens

and how they are treated..

growth of bacteria. You must take all of

the prescribed medicine or it can

How does it help fight infection?

~ It is a reaction to injury or infection that is characterized

by pain, redness, and swelling.

~ It is the body’s second line

of defense from pathogens.

The inflammatory response shows that body is attacking pathogens.

If a pathogen gets past the physical barriers, what system kicks in to fight the disease from the inside?

Your white blood cells produce antibodies that travel through

the lymphatic system to fight the

pathogens.

What are Immunizations?

A vaccine (shot) used to help prevent contracting a specific disease.

• A small amount of the pathogen is put in the body so the immune system can develop antibodies so if exposed to the same pathogen you can fight it off without getting it.
