Question 1

Pathogen-
Examples

Answer 1

-any organism that can cause disease
eg. bacteria, virus, parasite, fungi

Question 2

Innate/ non specific defence

Answer 2

-large range of responses
-first and second line
-no memory

Question 3

Adaptive/ specific defence

Answer 3

-immunological memory
-recognise and bind to specific antigen

Question 4

First line of defence

Answer 4

-skin
-nasal hairs
-stomach acid
-mucous membrane
-cilia
-urinary tract

Question 5

Second line of defence

Answer 5

-inflammatory response
-phagocytosis

Question 6

WBCs

Answer 6

Leukocytes
-phagocytes, monocytes, macrophages, dendritic cells

Question 7

Cells of the innate immune system

Answer 7

-mast cell
-granulocytes
-phagocytes- neutrophil, macrophage, dendritic cell
-natural killer cell

Question 8

Cells of the adaptive immune system

Answer 8

B cells
-memory and plasma
T cells
-helper and cytotoxic

Question 9

Phagocytosis

Answer 9

-WBC receptors recognise pathogen as foreign when pathogen interacts with phagocyte
-phagocyte engulfs pathogen
-lysosome digests pathogen
-pathogen breaks down into proteins and other molecules
-major histocompatibility complex binds to the membrane of the phagocyte to form an antigen presenting cell
