Immunology - German

Question 1

What are the 4 classes of pathogens

Answer 1

1. bacteria
2. Virus
3. fungi
4. parasites

Question 2

What is the role of the immune system?

Answer 2

• Kill pathogens
• Control disease
• repair tissue damage
• organ development
• maintain organ integrity

Question 3

What physical barriers does the body have to protect itself?

Answer 3

Skin & Mucosal surfaces
ALSO
Endogenous antimicrobial properties

Question 4

What are the 3 common immune effector mechanisms?

Answer 4

Phagocytosis
Granule release
Trageted cell death

Question 5

What are a few KEY differences between Innate Immunity and Adaptive immunity?

Answer 5

Innate:

• Rapid response (hours)
• Fixed response
• Limited pathogen specificity
• Consistent response

Adaptive: 
-Slow response (days-
  weeks)
- Flexible response
- Very selective pathogen 
  specificity
- Retains MEMORY

Question 6

A fixed response is an example of adaptive/innate immunity

Answer 6

Innate

Question 7

A rapid response is related to adaptive/innate immunity

Answer 7

Innate

Are all examples of what type of immunity

Answer 8

Innate

Are all examples of what type of immunity

Answer 9

Adaptive

Answer 13

Chemokines (indirect)

Question 14

What is the most common type of white blood cell in the body

Answer 14

Neutrophil

Question 15

Neutrophil, basophil, Eosonophil are all examples of innate/adaptive immunity?

Answer 15

Innate

Answer 16

Neutrophil

Question 17

How do macrophages kill and what do they promote?

Answer 17

Kill by phagocytosis

Promote - inflammation

Question 18

What is the difference between humoral and cellular immunity responses

Answer 18

Humoral - Antibody mediated

Cellular - Cell-cell interactions

Question 19

Antibodies are an example of ………….. response

Answer 19

Humoral (Also adaptive)

Question 20

What are the 2 types of T cells and what do they do?

Answer 20

(CD8) Cytotoxic cells - kill altered self cells

(CD4) Helper T cells - support other immune functions

Answer 23

FALSE

Question 24

List the basic process of pathogen resolution

Answer 24

1. pathogen infiltration
2. Immune cells respons
3. Inflammatory response
4. INNATE pathogen targeting
5. Pathogenic antigens presented in the lymph nodes
6. ADAPTIVE immunity intiated
7. Ongoing Immune response
