3. The processes of immunity are classified in which of the following ways?

a.	innate or acquired	c.	class A and class B
b.	rapid and long-term	d.	grade I and grade II

 

 

ANS:  A

 

	Feedback
A	Correct. The processes of immunity used by the body are classified as either innate (natural) or acquired. Innate or natural immunity consists of many factors relatively nonspecific. These include physical barriers such as skin, mucous membranes, and cough reflex. Natural immunity also includes nonspecific immune cells such as phagocytes and lymphocytes. Acquired immunity is a specific immunity, triggered then a person has had prior contact with a foreign agent. This activates the humoral system (B lymphocytes) and the cell-mediated system (T lymphocytes).
B	Incorrect. The processes of immunity used by the body are not classified as rapid and long-term.
C	Incorrect. The processes of immunity used by the body are not classified as class A and class B.
D	Incorrect. The processes of immunity used by the body are not classified as grade I and grade II.

4. What is the body’s main defense against viruses?

a.	T lymphocytes	c.	interferon
b.	B lymphocytes	d.	interleukin

 

 

ANS:  A

 

	Feedback
A	Correct. The body’s main defense against viruses is the T lymphocytes which direct and regulate the immunologic response by secreting lymphokines.
B	Incorrect. The body’s main defense against viruses is not the B lymphocytes.
C	Incorrect. The body’s main defense against viruses is not interferons.
D	Incorrect. The body’s main defense against viruses is not interleukins.

5. The chemical mediators or messages communicating throughout the immune processes are:

a.	interferon	c.	cytokines or interleukin
b.	helper T cells or T lymphocytes	d.	B lymphocytes

 

 

ANS:  C

 

	Feedback
A	Incorrect. The chemical mediators or messages communicating throughout the immune processes are cytokines or interleukins.
B	Incorrect. The chemical mediators or messages communicating throughout the immune processes are cytokines or interleukins.
C	Correct. The chemical mediators or messages communicating throughout the immune processes are cytokines or interleukins. These include the lymphokines, produced by the lymphocytes, and the monokines, produced by monocytes and macrophages.
D	Incorrect. The chemical mediators or messages communicating throughout the immune processes are cytokines or interleukins.
