  1. 3. Cells Antibody-secreting effector B cells
  2. 5. Gland in the thoracic cavity of the heart (where T cells mature)
  3. 7. Presentation MHC binds to a piece of an antigen within the cell and brings it to the surface.
  4. 8. response Chemicals cause blood vessels to leak fluid and swell
  5. 11. immunodeficiency virus the infectious agent that causes AIDS. HIV is a retrovirus
  6. 15. Killer A type of white blood cell that can kill tumor cells and virus-infected cells
  7. 16. Immune Response The acquired immune response elicited on second or subsequent exposure to a particular antigen. (more rapid, stronger, and of longer duration than primary)
  8. 19. Programmed cell death
  9. 20. Cells A muscle cell or gland cell that performs the body’s responses to stimuli.
  10. 21. The most abundant type of white blood cell. They are phagocytic cells.
  11. 24. Immune Response The selective proliferation and differentiation of lymphocytes the first time the body is exposed to an antigen.
  12. 25. A protein released by animal cells that has the property of inhibiting virus replication.
  13. 26. cells An antigen-presenting cell that is particularly efficient in presenting antigens to naive helper T cells, thereby initiating a primary response.
  14. 27. cytokines with functions that include attracting white blood cells to sites of infection.

  1. 1. immune response One of the two branches of acquired immunity; the activation and clonal selection of cytotoxic T cells, which directly destroy certain target cells.
  2. 2. immunity Immunity conferred by the natural exposure to an infectious agent.
  3. 4. immune response One of the two branches of acquired immunity; the activation and clonal selection of B cells, resulting in production of secreted antibodies that circulate in the blood and lymph.
  4. 6. A phagocytic cell present in many tissues that function by destroying microbes.
  5. 9. shock an acute, whole body, life-threatening, allergic response
  6. 10. immunity The kind of defense that is mediated by phagocytic cells, antimicrobial proteins, the inflammatory response, and natural killer cells. It is present before exposure to pathogens and is effective from the time of birth
  7. 12. Any foreign molecule that is specifically recognized by lymphocytes and elicits a response from them.
  8. 13. Large marsupial
  9. 14. cells A cell filled with basophil granules, found in numbers in connective tissue and releasing histamine and other substances during inflammatory and allergic reactions.
  10. 17. disease an immunological disorder in which the immune system turns against itself
  11. 18. T-cell central to the acquired immune responses; responds to peptide antigens displayed on antigen-presenting cells and in turn stimulates the activation of nearby B cells and cytotoxic T cells.
  12. 22. A type of white blood cell with low phagocytic activity
  13. 23. immunity immunity conferred by transferring antibodies from an individual who is immune to a particular infectious agent to someone who is not
