TEAS SCIENCE: Immune System

Question 1

Which immune system is a “nonspecific response”?

It’s a collection of non specific barriers and cellular responses that serve as an inborn first, and second line of defense against pathogens?

Answer 1

innate immune system (remember it is not passive - it’s active! Just 2nd in line)

Question 2

Which immune system “responds to specific antigens”?

It’s a kind of passive or active immunity in which antibodies to a particular antigen are present in the body?

Answer 2

adaptive immune system

Question 3

pathogens can enter the body through ____ nodes, which contain a large # of antigen-presenting cells that can trigger the adaptive immune system

Answer 3

lymph nodes

Question 4

The following are part of which immune system? are they internal or external?

skin, hair, mucus, ear wax, secretions (acid, salt, enzymes), Normal Flora

Answer 4

innate immune system, external

Question 5

The following are part of which immune system? are they internal or external?

Antimicrobials, Inflammation, Interferons, Complement, NK (natural killer) lymphocytes, phagocytes (including APC)

Answer 5

innate immune system, internal

Question 6

The following are part of which immune system? is it reactive or preventative?

Cytotoxic T-cells that kill pathogens

Answer 6

adaptive immune system, reactive

Question 7

The following are part of which immune system? is it reactive or preventative?

B-cells that produce antibodies

Answer 7

adaptive immune system, preventative

Question 8

A Complement is the group of proteins in blood serum and plasma that works with antibodies to destroy particulate antigens.

Is this part of the innate or adaptive immune system?

Answer 8

innate
