What is a pathogen? - Answer An organism that causes disease. Can be a virus, bacteria, fungi,
parasite, or prion.
What is the function of a basophil? - Answer Have granules containing histamine and heparin
What is the function of dendritic cells? - Answer Antigen-presentation
What is the function of eosinophils? - Answer To attack parasites
What is the function of neutrophils? - Answer The most abundant while blood cell
What is the function of natural killer cells? - Answer To attack virus-infected cells
What is the function of T-lymphocytes? - Answer To kill virus infected cells and activate
macrophages/B cells
What is are the antigen-presenting cells? - Answer Dendritic, lymphocytes, macrophages, and
monocyte
The pathophysiology associated with AIDS is an example of a ________________ response by
the immune system - Answer Lack of
What function is most directly lost when helper T-cells die? - Answer The ability to activate B
lymphocytes
If the barrier protections fail to exclude pathogens, the first line of cellular defense against the
pathogens are the _________. - Answer Phagocytes
What is the function of the chemotaxis released by some leukocytes? - Answer To attract
additional immune cells
What are the characteristics of acquired immunity? - Answer Adaptive immunity, cell
mediated immunity, humoral immunity
, In order for a lymphocyte to respond to an antigen, what must the antigen do? - Answer Bind
to specific receptors on the lymphocyte membrane
In people with celiac disease, gluten is able to enter the body. What type of immune system is
being compromised here? - Answer Physical barriers
Gluten can act as an antigen. What is an antigen? - Answer A substance that triggers an
immune response
Which part of the immune system is specifically involved in responding to antigens? - Answer
Acquired immunity
How does the body learn to recognize an antigen? What is the first response? - Answer
Phagocytes ingest the antigen, and then insert a portion on their surface
How does the body learn to respond to a specific antigen? What happens after the phagocyte
displays a portion of the antigen in its membrane? - Answer Activated lymphocytes make
antibodies, antigen presenting cells present antigens to T lymphocytes, clonal expansion of
lymphocytes, T lymphocytes activate B lymphocytes
What type of cells make antibodies? - Answer Plasma B cells
What is the major function of antibodies and celiac disease and in general? - Answer They tag
pathogen an abnormal cells for distruction
What type of cells recognize and destroy antibody coated cells or pathogen's? - Answer
Macrophages and neutrophils
In celiac disease, the body starts to secrete anti-gluten and antigliadin antibodies. This causes
changes in the brain. Why? - Answer The cells in the brain have cell surface proteins that are
similar in structure to gluten and gliadin
How is an auto immune disorder different than an allergy? - Answer The body is attacked by
itself in an auto immune disorder, while an allergy is an inappropriate response to a non-
harmful subject
A patient with celiac disease also ask her doctor if it's OK to cheat occasionally. What do you
think? - Answer No, because once the immune system is activated it will always react to gluten
