- The study of immunology may sound complicated, but in fact, the premise is simple.
- Immunology deals with how the body differentiates what is, "self" from "non-self" or foreign.
- The details of how the body does this can get quite complicated.
- 'Immunity' refers to all of the different mechanisms that the body uses to protect itself from those things that are "non-self."
- Foreign materials that the body may reject include bacteria, viruses, chemicals, drugs, plants, etc.
