Chapter 11: Innate + Adaptive Immunity Flashcards
1
Q
Innate Immunity
A
- nonspecific
- natural resistance that a person is born with
- first line of defence
- mucous membranes, skin, GI tract
2
Q
Adaptive Immunity
A
- specific immunity
- responding less rapidly than innate immunity but more effectively
- second line of defense
3
Q
Cytokines
A
- soluble proteins secreted by cells of both the innate and adaptive immunity
- may induce fever
4
Q
Chemokines
A
- cytokines that stimulate the growth and differentiation of bone marrow progenitors of immune cells
5
Q
Colony-Stimulating Factors
A
- stimulate growth and differentiation of bone marrow progenitors of immune cells
6
Q
Principal Cells of the Innate Immunity
A
- neutrophils
- lymphocytes
- accessary cells
7
Q
Neutrophils
A
main phagocyte in early inflammation
8
Q
Lymphocytes
A
cells that specifically recognize and respond to foreign antigens
9
Q
Accessory Cells
A
- macrophages and dendritic cells
- function as antigen-presenting cells by the processing of a complex antigen into epitopes requires for the activation of lymphocytes
10
Q
Natural Killer Cells
A
innate immunity
- recognize and eliminate cells infected with viruses; our cells gone rogue
- inhibitory and activating receptors to allow differentiation between normal and abnormal cells
- procedure cytokines and toxic
11
Q
Antigen
A
substances foreign to the host that can stimulate an immune response
12
Q
Antibody
A
recognize antigens
- receptors on immune cells
- secreted proteins
13
Q
Immunogen
A
triggers the production of antibodies by T Lymphocytes
14
Q
Immunogen
A
triggers the production of antibodies by T Lymphocytes
15
Q
Regulatory Cells
A
type of immune cell (1)
- assist in orchestrating and controlling the immune response
