  1. The study of the reactions of a host when foreign substances are introduced into the body
    Immunology
  2. Foreign substances that induce such an immune response
    antigens
  3. The condition of being resistant to infections.
    immunity
  4. Discovery of small pox vaccine
    Edward Jenner
  5. —Deliberately exposing an individual to material from smallpox lesions to reduce effects of the disease
    —Variolation
  6. —Procedure of injecting immunogenic material into the body to induce immunity
    Vaccination
  7. —Live organisms that have been changed by heat, age, or chemical means
    attenuated vaccine
  8. Protection that is always present
    —Innate immunity
  9. Protection that arises by an immune response
    Adaptive immunity
  10. Substances, usually proteins, present in any bodily fluid
    —Humoral
  11. —Innate and adaptive further divided into:
    • Humoral
    • Cellular
  12. —Serum factors in the blood formed in response to exposure to foreign substances
    —Antibodies
  13. The study of the noncellular components in the blood
    Serology
  14. Process by which particulate antigens, such as cells, aggregate to form larger complexes when a specific antibody is present
    Agglutination
  15. The combination of a soluble antigen with a soluble antibody to produce visible insoluble complexes
    —Precipitation
  16. Functions in early stages of host defense in response to an antigen
    Natural response
  17. When antigen causes a disease, it is a?
    pathogen
  18. Cells engulf and degrade antigen
    Phagocytosis
  19. What are the two populations of phagocytes?
    • Macrophages
    • Neutrophils
  20. Soluble proteins that regulate immune responses
    Cytokines
  21. Defend against virally infected cells and some tumor cells.
    Natural Killer Cells
  22. —Main host defense mechanism activated in response to parasitic infections, particularly helminths.
    —Eosinophils
  23. When basophils degranulate in excessive amounts, an enormous hypersensitivity results
    anaphylaxis
  24. —They are the most potent phagoctyic cell in the tissues
    Dendritic Cells
  25. Most widely used indicator of acute inflammation
    —Latex agglutination test for elevated levels in the serum
    C-reactive protein
  26. —A series of serum proteins that are normally present
    Overall function: Mediation of inflammation
    Complement
  27. Mechanisms activated in tissue damage referred to a:
    Inflammatory Response
  28. Designed for antigens and antibodies very small in size or in very low concentrations
    Indicator-Labeled Immunoassays
  29. Indicator-Labeled Immunoassays:
    The presence of antigens or antibodies is determined _____________ by using a labeled reagent.
    Indirectly
  30. Make it possible to quantitate antigen or antibody
    Labels
  31. Labels:
    The substance to be measured is known as an
    Analyte
  32. Indicator labels for immunoassays fall into four broad categories:
    • Radioactive isotopes
    • Fluorochromes
    • Enzymes
    • Chemiluminescent tags
  33. The key cell involved in the immune response
    Lymphocyte
  34. Two primary lymphoid organs
    • Thymus
    • Bone Marrow
  35. Effector cells serving a regulatory role
    T lymphocytes
  36. Produce antibody
    B lymphocytes
  37. Large, granular, & plays a role in both the innate &
    adaptive immune response
    NK Cell
