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.
True

Question 2
Lymph nodes act like a filter in the kitchen sink to pull invading
pathogens out of the blood and degrade them.
True
False
Question 3
Fluid that has passed through the lymph nodes will be delivered back
to the blood through the thoracic duct.
True
False
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.
True
False
Question 5
Our immune system is divided into two major systems. What are
they?
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.
Answer:
Question 7
Essay: Our immune cells have developed a clever trick to randomly
generate billions of antibodies through chromosomal rearrangement
before birth.
Question:
1. Explain the function of these billions of different antibodies,
2. AND explain how this leads us to greater protection against infection
by pathogens.
Answer:
1.
2.
Question 8
What cell surface molecule is a characteristic marker for T helper cells?
CD4
Transferrin receptor
CD8
Question 9
What type of lymphocyte generates antibodies?
B-cells
T-cells
Macrophages
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.
True
False
Question 14
Response is tailored to specific antigens.
True
False
Question 15
Response is maintained by memory cells.
True
False
Question 16
Response is mediated by B and T cells
true
false
