Pathophysiology chapter 3,4,5, EXAM Questions
and Answers
1. What is critical in the initiation of immune response? correct answer:
Macrophage- B and T Lymphocytes
2. Macrophages develop from what? correct answer: Monocytees
3. What are the two groups of lymphocytes that determine which
type of immu- nity will be initiated? correct answer: B lymphocytes and T
lymphocytes
4. T lymphocytes arise from? correct answer: Stem cells
5. what immunity response develops when T cells link with and
antigen and is recognized as an invader then destroys it? correct answer:
Cell-mediated immunity
6. Antigen correct answer: Foreign substance or component of cell that stimulates immune response
7. Antibody correct answer: Specific protein produced in humoral response to bind with antigen
8. Autoantibody correct answer: Antibodies against self antigen; attack's body's own tissue
9. B lymphocyte correct answer: Humoral immunity-activated cell becomes and antibody-
producing plasma cell or a B memory cell
10. T lymphocyte correct answer: White blood cells; cell-mediated immunity
11. Immunoglobulins correct answer: IgG IgM IgA IgE IgD
12. which lymphocyte acts primarily against bacteria and viruses?
correct answer: B lymphocytes
13. Natural Active Immunity correct answer: Acquired by direct exposure to and
antigen, ex- when a person has an infection and then develops antibodies
14. Artificial Active Immunity correct answer: Develops when a specific antigen is
purposefully introduced into the body, stimulating the production of antibodies, ex- a vaccine
15. Passive Natural Immuniy correct answer: Occurs when IgG is transferred from
mother to fetus, ex- through the placenta or breast milk
16. Passive Artificial Immunity correct answer: Results from the injection of
antibodies from another person, ex- admin- istration of rabies antiserum or snake antivenom
17. How many Hypersensitivity reactions are there? correct answer:
4
1/
11
, 18. Hypersensitivity or allergic reaction correct answer: Unusual and perhaps
damaging immune responses to normally harmless substances
19. Hypersensitivity Reaction Type 1 correct answer: Allergic Reaction
20. Signs of Allergic Reaction correct answer: Skin rashes, hay fever, vomiting, and
anaphylaxis
21. What occurs during the second exposure leading to an allergic
reaction? correct answer: Large amounts of chemical mediators are released from mast
cells into the general circulation very quickly
22. Where dose the problem occur with and allergic reaction? correct
answer: IgE attach to Mast cells, with the second exposure mast cells release histamine
