Q

Suppressor T cells

A

Turn off cell mediated response

17
Q

B Cells

A

Differentiate into plasma cells that are filled with ribosomes
Make and secrete antibodies
Antibodies bind to pathogen - decreases pathogenic activity

18
Q

Natural killer cells

A

Stimulate cells to perform apoptosis

19
Q

Adaptive immunity

A

Macrophages engulfs pathogen
Present antigen on surface
Detected by specific helper T cells
T cells rapidly divide
Stimulate - phagocytic activity by macrophages
-inflammatory response
- Killer T cells (cell mediated) - kill pathogen or stimulate apoptosis (NK)
- B cells (humoral) - plasma cells produce antibodies which stimulate macrophages to engulf and destroy. Memory B cells produced

20
Q

Polycynthemia

A

High RBC count

21
Q

Leukaemia

A

High WBC count

22
Q

Thrombocynemia

A

Platelet levels high

23
Q

Anaemia

A

Low Hb

24
Q

Leukopenia

A

Low WBC

25
Q

Thrombocytopenia

A

Low platelet count

26
