Illness

2

establishment of a pathogen in a susceptible host

infection

3

freedom from and prevention of disease-causing contamination

asepsis

4

3 main defenses against infection

Normal Flora
Inflammatory process
Immune response

5

substances that provokes an adaptive immune response

antigen

6

Types of adaptive immunity

humoral and cellular

7

defense system that uses WBC to produce B lymphocytes produced in response to antigens or pathogens

Humoral immunity

transmission occurs when microorganism is dispersed by air, then inhaled or deposited

airborne transmission
