What is considered the first line of immunological defence?

A

Phagocytic Cells

B

Gut Flora

C

Physical Barriers

D

Lymphatic Tissue

Question 2 of 7

What are the primary roles of macrophages?

(Select all that apply)
A

To send first stage cytokine signals to the rest of the immune system when infection or physical trauma are present

B

To engulf and break down pathogens and foreign material

C

To respond to antibody presentation and instigate the correct response

D

To bind to infected cells and instigate programmed cell death

Question 3 of 7

What percentage of the immune system is made up of Neutrophils?

A

36%

B

48%

C

12%

D

61%

E

70%

Question 4 of 7

What is the role of selectin?

A

To allow neutrophils to differentiate and increase in number.

B

To allow neutrophils to adhere to the endothelium for accurate delivery to the site of infection.

C

To allow neutrophils to adequately identify their target and instigate their effects more efficiently.

Question 5 of 7

Which of these statements adequately describes ONE of the roles that Natural Killer Cells play?

A

They secrete a burst of free radicals that destroy pathogens

B

They penetrate a target cell with perforin and inject it with a group of enzymes that destroy the target cells

C

They marke the target cell with a surface marker that other cells of the immune system can identify

Question 6 of 7

Which statement best describes the activity of immunomodulatory polysaccharides?

A

They enter our circulation where they can bind to certain white blood cells and make them behave more aggressively towards pathogens

B

They interact with cell populations in the Peyer’s Patch that triggers an alarm response that stimulates an increase in the production and activity of certain white blood cell types

C

They increase the rate of neutrophil migration to the site of infection

Question 7 of 7

How does Zinc influence the immune system?

A

It is a key component in cytokine production

B

It helps inactive cell types differentiate into their active states

C

It is used by white blood cells to code genes that regulate the way in which they interact with pathogens
