adaptive immunity Flashcards
1
Q
antigen
A
protein from pathogen - generates immune response
2
Q
pathogen
A
disease causing organism
3
Q
helper t-cells
A
- activated by antigen presenting cell (present the antigen)
- activate killer t-cells
- and call in b-cell
4
Q
killer t-cells (cellular immunity)
A
- find infected cells and only destroy them
5
Q
memory b-cell and t-cell
A
- remain after the battle
- ready to respond quickly
6
Q
b-cell (in humoral immunity)
A
- once called in by helper t-cell
- make antibodies and release them into blood
- antibodies will find where pathogen is and will stick to it (deactivates it)
7
Q
where do b-cells become immunocompetent
A
the bone marrow
8
Q
where do t-cells become immunocompetent
A
the thymus
9
Q
adaptive immunity requirements
A
- has to be triggered or sensitized to pathogen
- responds to antigen (specific)
- recognize (antigen)
- remove (virus)
- remember (antigen)
