Nonspecific (Innate) And Specific (Acquired) Defenses

Front 1

Why are specific (acquired) defenses tailor-made?

Back 1

to counter a particular invading pathogen and protect against cancer

Front 2

So what type of defense will cancer utilize by the body?

Back 2

Specific acquired defenses

Front 3

What is the polysaccharide molecule that the body recognizes as nonself?

Back 3

an antigen

Front 4

Where are antigens found?

Back 4

microbes, foreign cells, or on cancer cells

Front 5

How can an autoimmunce disease be associated with bone marrow?

Back 5

t-cells become self-reacted antigens in the thymus, if they are not destroyed when they escape, you have an autoimmune disease

Front 6

What kind of immunity are b cells responsible for?

Back 6

antibody-mediated immunity

Front 7

A bacterium may have numerous what that can stimulate antibody production?

Back 7

antigenic determinants

Front 8

B cells are responsible for what type of immunity? (both names)

Back 8

antibody-mediated immunity or humoral immunity

Front 9

T cells are responsible for what type of immunity?

Back 9

cell-mediated immunity

Front 10

How are B and T cells capable of recognizing an antigen?

Back 10

Because they have specific receptor molecules on their surface which exactly fit individual antigens (like a lock and a key)

Front 11

Where does the diversification of specific receptor molecules occur?

Back 11

during the maturation process

Front 12

It is estimated that for the million or so antigens we encounter in our lifetime, what is equally probabl?

Back 12

we have an equal number of of specific lymphocytes for each possible antigen
