1
Q

- forms attack complex
- causes hole ( deflates / kills bacteria )
2
Q
B cells
A
- attach free virus
- antibody reaction
- mature in bone marrow
responsible for antibodies
3
Q
T cells
A
- attack infected cells
- mature in thymus or spleen
infected cells
4
Q
B lymphocytes
A
- bind to antigen
- divide and differentiate into:
PLASMA CELLS
MEMORY CELLS
5
Q
Plasma cells
A
secrete antibodies
6
Q
Memory cells
A
stronger second response
(clones of original B cells)
ie. next time exposed to the virus = bigger response
7
Q
T lymphocytes
A
HELPER T CELLS
- secrete cytokines
- crank up immune response
- increases B and T cells
CYTOTOXIC T CELLS
- direct attack
- recognize antigen marker
SUPPRESSOR T CELLS
- limits response
- keeps it in line
8
