APHY 201 Ch 24 Immune System Ivy Tech Questions with Correct Answers
Question 1:
Ability of the body to protect itself and resist disease.
Answer:
Immunity
Question 2:
1. recognize and remove abnormal self cells, 2. remove dead and damaged cells, 3. protects the
Answer:
immune system major function
Question 3:
What two divisions make up the immune system?
Answer:
body from pathogens
Question 4:
What is the innate defense system composed of? Inflammation most important mechanism.
first line of defense
mantle, tears, mucous, enzymes)
second line of defense (innate immunity)
Answer:
Innate and adaptive
First line is external body membranes (skin and mucosae). Second line is made of antimicrobial
proteins, fever, phagocytes, and other nonspecific cells designed to inhibit spread of invaders.
physical (skin and mucous membranes), mechanical (cilia, fluid flow), chemical barriers (acid
protective cells, chemicals, and fluids; inflammation and phagocytosis; nonspecific
Question 5:
Production of specific antibodies (B lymphocytes) or cell-mediated immunity (T lymphocytes)
Answer:
third line of defense (specific immunity)
,Question 6:
What must the immune system be able to distinguish?
self (healthy/defective cells) from non-self (bacteria, viruses, parasites, allergens, other
pathogens)
Answer:
pathogenA disease causing agent immunogenssubstances that induce an immune response
antigensa toxin or other foreign substance that induces an immune response in the body,
especially the production of antibodies.pathogenA disease causing agent
immunogenssubstances that induce an immune response antigensa toxin or other foreign
substance that induces an immune response in the body, especially the production of
antibodies.
pathogen
A disease causing agent immunogens
substances that induce an immune response antigens
a toxin or other foreign substance that induces an immune response in the body, especially the
production of antibodies.

production of antibodies.
Question 7:
Hormone-like chemicals facilitating communication between brain and immune system.
Answer:
cytokines
Question 8:
Immunity that is present before exposure and effective from birth. Rapid response to a broad
immune system.
adaptive immunity
consists cell-mediated and humoral (antibody-mediated) immunity contact-dependent signaling
Answer:
innate immunity
range of pathogens. Inflammation and phagocytosis is characteristic. "Not remembered" by the
immunity or resistance to a specific pathogen; slower to respond, has memory component;
Question 9:
What is the response to invading pathogens?
Answer:
surface receptors on one cell recognize and bind to surface receptors on another cell
, Question 10:
What is the adaptive defense system composed of?
Answer:
assistance and coordination of response, 4. destruction or suppression of the pathogen
Third line of defense attacks particular foreign substances and takes longer to react than innate
Question 11:
When is second line of defense utilized? tissues.
Answer:
system. Utilizes B and T lymphocytes.
If surface barriers are breached by nicks or cuts, then second line of defense must protect
deeper
Question 12:
Pattern Recognition Receptors (PRRs)
Answer:
Macrophages, dendritic cells, neutrophils, eosinophils, basophils
proteins on or in cells that recognize specific compounds unique to microbes or tissue damage,
Question 13:
Toll-like receptors (TLRs)
-A type of PRR
-Recognize PAMPs
Answer:
allowing the cells to sense the presence of invading microbes or damage
-Set in motion a cascade of events inside the cell that amplifies and orchestrates a defense
Question 14:
Pattern Associated Molecular Patterns (PAMPs) the microbes as foreign
-Serve as "RED FLAGS" for phagocytes and other cells of immunity
Answer:
response to the pathogen
-Molecules on the surfaces of many types of microbes that are not present on host cells that
mark
-patterns are found on bacterial cell walls, DNA, lipoproteins, carbohydrates, or other
structures
