2
Q
What are the 4 main classes of infectious microorganisms?
A
- Bacteria

- Fungi
- Parasite
3
Q
What is the biggest difference between the inate and adaptive immune responses?
A
Inate is much faster
4
Q
Give an example of innate immunity
A
- Anatomical barriers
- Fevers
- Phagocytes
- Inflammation
5
Q
What happens during inflammation?
A
- Blood vessels dilate, leak, ‘sticky’
6
Q
What do sensor cells do?
A
- Produce mediators
- Like chemokines and cytokines

Q
What do dendritic cells do?
A
- Bridge between innate and adaptive immune system
8
Q
What does the spleen do?
A
- It filters the blood
9
Q
What is the difference between cell-mediated immunity and antibody-mediated immunity?

- antibodies: Antibodies circulate
10
Q
What are the 3 steps of antibody production?
A
- Sensitisation
- Activation
- Division and Differentiation
