Module 4 Quiz Chapter 3 Part 1
Questions 1-4
The following series of 4 questions deals with the function of the
lymph nodes. Answer each as a separate question. More than one
may be true.

Do not write any answer here.

Question 1
Lymph nodes act like a filter in the kitchen sink to pull invading
pathogens out of the lymph fluid and degrade them.

Question 2
Lymph nodes act like a filter in the kitchen sink to pull invading
pathogens out of the blood and degrade them.


Question 3
Fluid that has passed through the lymph nodes will be delivered back
to the blood through the thoracic duct.



Question 4
Lymph nodes scan for invading pathogens: Macrophages can
present antigens to B- and T-cells in the lymph node to warn them of
invading pathogens in the nearby tissues.


Question 5
Our immune system is divided into two major systems. What are
Innate and adaptive

humoral and cell-mediated

innate and non specific

physical barriers and chemical barriers

Question 6
Essay: Explain this statement: Many of the symptoms that we feel
when we are sick are not a direct outcome of the pathogen, but an
expression of our own Inflammatory Response.

The answer for this is not directly written in the book. It will require
some online research and some thought.


Question 7
Essay: Our immune cells have developed a clever trick to randomly
generate billions of antibodies through chromosomal rearrangement
before birth.

1. Explain the function of these billions of different antibodies,

2. AND explain how this leads us to greater protection against infection
by pathogens.

Question 8
What cell surface molecule is a characteristic marker for T helper cells?

Transferrin receptor


Question 9
What type of lymphocyte generates antibodies?



Natural Killer cells

Question 10
In Chapter 3, we learned that our bodies have two major types of immune
defense, the Innate and the Adaptive Immune Systems. The major advantage
of the adaptive immune system over the innate is:
its ability to create an immunological memory after an initial response

its ability to have an immediate response to pathogens that breach physical barriers
its ability to protect the individual from pathogens regardless of experiences

Question 11
Which of the following cells related to the immune system are housed in
the lymphatic system?
B and T cells

red blood cell

epithelial cell

glial cells

Question 12
Figure 3-14 on p. 34 of the textbook shows the difference between the
secondary immune response and the primary immune response. Be sure
that answer both of the following questions:
1. Explain what the two curves are depicting.
2. Why do they have different shapes?

Questions 13-16
This set of 4 TRUE/FALSE questions deals with adaptive immunity. Answer
these separately.

Question 13
Response is to recognized “self” antigens.


Question 14
Response is tailored to specific antigens.



Question 15
Response is maintained by memory cells.



Question 16
Response is mediated by B and T cells
