1	EMP 192 Exam 2 Review Part 2
2	Question Name all secretions made by the anatomical barrier that attack bacteria.
3	Answer Fatty and Lactic Acid Sweat Tears Saliva
4	Question What are the bodies 3 lines of defense against pathogens?
5	Answer Anatomical Inflammatory Immune
6	Question How can you classify each line of defense?
7	Answer Anatomical External and Non-specific Inflammatory Internal and Non-specific Immune Internal and Specific
8	Question What does each cell carry on it surface as its specific marker? Hint – HLA
9	Answer Anitgen
10	Question State the main difference between Passive and Active Acquired Immunity.
11	Answer Active Acquired Immunity The individuals body develops the immunity after exposure to a specific antigen. Passive Acquired Immunity Transferred to the individual from an outside source. Example – mother to baby. baby didn’t develop the antibodies, mom did and passed them to baby.
12	Question What is the main difference between and T lymphocyte and a B lymphocyte?
13	Answer T lymphocytes Directly attack the pathogen B lymphocytes Develop and antibody or memory cell to attack a specific
14	Question What is humoral immunity?
15	Answer The development of a memory cell, B lymphocyte, to develop a long-term immunity to a specific antigen.
16	Question Explain the difference between and immunogen and an immunoglobulin.
17	Answer Immunogen – an antigen that is able to trigger an immune response Immunoglobulin – antibodies; proteins, produced in response to foreign antigens
18	Question When talking about HLA and tissue transplants. Who in the immediate family what be most reliable with a match. Mother Father Paternal Twin Identical Twin
19	Answer Identical Twins They com from the same fertilized egg. Thus sharing the identical DNA. Same DNA creates the same HLA.
20	Question Where do lymphocytes come from?
21	Answer All cell originate from stem cells. T lymphocytes mature in the thymus B lymphocytes mature in the lymphatic tissue outside the thymus
22	Question The cell created by mature B lymphocytes that will create a swifter and stronger immune response when encountering an antigen for the second time.
23	Answer Memory cell
24	Question What are direct and indirect functions of antibodies on antigens?
25	Answer Agglutination Precipitation Neutralization Enhancement of Phagocytosis Activation of plasma proteins
26	Question Through the direct and indirect effects of antibodies on antigens what are the four main functions
27	Answer Neutralization of Bacterial toxins Neutralization of Viruses Opsonization of Bacteria Activation of Inflammatory processes
28	Question In the first phagocyte to reach the inflamed site and ingest bacteria.
29	Answer Neutrophils They are mature cells that can readily ingest bacteria Please remember that macrophages will do the same thing but first must mature from a monocyte. Thus slower reaction.
30	Question What is a basophil?
31	Answer This cell (leukocyte) reacts within the blood volume the same way a mast cell works within the tissue. Basophils will release histamine to control vessel size.

33	Statement Spend some time studying the areas in which each question comes from. Have a working knowledge of the aspect of inflammation and immunity and you should do fine.
