16
Q

what are the 2 kinds of adaptive immunity

A

1) anti-body mediated or humoral immunity

2) cell-mediated immunity

17
Q

are dendritic cells innate or adaptive

A

innate

18
Q

what is anti-body mediated immunity

A

production of antibodies by B lymphocyte derivatives known as plasma cells

19
Q

what is cell-mediated immunity

A

production of activated T lymphocytes to directly kill unwanted cells

20
Q

what is specificity

A

lymphocytes recognizing different antigens

21
Q

B lymphocytes

A

inactive lymphocytes

secrete antibodies

22
Q

T lymphocytes

A

do not secrete antibodies

23
Q

where are T cells made & mature

A

bone marrow & thymus

24
Q

what are the 2 types of T cells

A

1) helper T cells

2) CD8 cells (cytotoxic & killer T cells)

25
Q

what is the function of helper T cells?

A

activate macrophages & phagocytosis, make cytokines, activate B cells, becomes plasma cell

26
Q

what is the function of CD8 cells?

A

destroy any foreign cells by binding to antigen which can kill cell directly or through use of enzyme
