1

What are the 3 types of B cells

1. Short lived Plasma cells
2. Long lived plasma cells
3. Central Memory B cells

2

Where are short lived plasma cells produced

in lymphoid follicles of secondary lymphoid organs

3

where do short lived plasma cells travel to

bone marrow and spleen

4

what do short lived plasma cells do

produce lots and lots or antibodies

5

how long do short lived plasma cells live for

few days

6

where are long lived plasma cells produced

lymphoid follicles of secondary lymphoid organs

7

where do long lived plasma cells travel to

bone marrow

8

what do long lived plasma cells do

continuously produce modest amounts of antibodies

9

T/F long lived plasma cells provide life long protection

True

10

what is the purpose of central memory B cells

-maintain a pool of central memory B cells
- replace long lived plasma cells when old and dying

11

what do central memory B cells do when we encounter an antigen again

quickly proliferates making more short lived plasma cells

12

T/F t cell memory is similar to B cell memory

True

13

what are the 3 types of T cells (after activation)

1. Effector T cells
2. memory Effector T cells
3. Central Memory T cells

14

where do the central memory T cells travel to

stay on the secondary lymphoid organ

15

what is the job of Effector T cells

travel to battle site and fight

16

what is the job of Memory Effector T cells

travel to battle site and remain (up to 10 yrs)

17

T/F after an immune response that are more cells specific to the invader than virgin cells

true

18

T/F during subsequent infections we usually can feel we have been infected

False

19

What is the T cell equivalent to a Long lived plasma B cell

THERE IS NONE (we dont want a constant stream of pro-inflamatory cells)

20

Does our innate immune system update

No, stays static

21

What makes adaptive immunity different from innate immunity

-expandable memory
-remembers invaders
-each is unique to the person
