• pasteur

• koch

• lister

• metchnikoff

In which organism were phagocytes first reported?

• bacteria

• amoeba

• red blood cells

• starfish larvae

Which is not a component of innate community

• skin

• inflammation

• fever

• antibody

which is not involved in adaptive immunity

• tear flow

• antibody

• T cell

• B cell

Skin and mucous membranes are mostly involved in

• innate immunity

• adaptive immunity

• autoimmunity

• irregular immunity

skin and mucous membranes

• are the first line of innate immunity

• are the first line of adaptive immunity

• act as physical barriers to infection

• contain antimicrobial secretions

• are the first line of innate immunity, are the first line of adaptive immunity, AND contain antimicrobial secretions

interferons, complement, lysozyme, and lactoferrin are all examples of

• specific antimicrobial factors

• immune enzymes

• nonspecific antimicrobial factors

• cytokines

normal microbiota

• are the organisms that typically reside on and in your body

• protect against infection by pathofens

• enhance infection by pathogens

• play no role in affecting pathogen growth

• are the organisms that typically reside on and in your body AND protect against infection by pathogens

Iron

• is required by microorganisms

• binds to lactoferrin

• is necessary for the functioning of some enzymes

• all choice are correct

Factors that work generically against any foreign substance entering the host are described as

• innate immunity

• specific immunity

• irregular immunity

• immune metabolism
