Secondary Def

Question 1

Antigens

Answer 1

Chem markers on the pathogen

Question 2

Phagocytes

Answer 2

Engulf and digest pathogens

Question 3

Neutrophils

Answer 3

Multi lobed nucleus Mfd bone marrow,short lived, contain lysosomes
Engulf and digest pathogens

Question 4

Macrophage

Answer 4

Initiate spec response to invade pathogen eg APC
Ensures APC isn’t mistaken as foreign

Question 5

Ag presentation

Answer 5

Move to come in contact with it’s specific t and B cells to activate full immune response so increases contact chances

Question 6

Specific immune response

Answer 6

Cytokine= stimulate differentiation and activity of marcophage B and t cells
Activate B and t = clonal selection to prod ab and memory for ltm imm

Question 7

Specific immune response

Answer 7

B and t = wbc w specialized receptors, neutralise ag
Prod immunological memory

Question 8

T lymphocytes

Answer 8

Helper=release cytokine to stimulate B to develop and stim phagocytosis
Killer= attach and kill host body cells w foreign ag
Memory= ltm immunity
Regulator= shut immune response after pathogen removed

Question 9

B lymphocytes

Answer 9

Plasma Mfd and secrete ab
Memory immunological memory

Question 10

Cell signalling

Answer 10

Macrophage= monoamines attract neutrophils to stim B diff and release ab
T and m= interleukins stim clonal exp and diff BT
Interferon inhibit virus rep and stim t killer activity
