The flashcards below were created by user bbhagan on FreezingBlue Flashcards. What would you like to do?


  1. interferon (interferes with viruses ability to replicate)
    A chemical secreted by virus-infected cells that helps to protect neighboring cells from infection
  2. Tumor necrosis factor
    A chemical that stimulates macrophages and causes cell death in cancer cells
  3. antibodies
    proteins that are produced by the body to bind to a specific foreing antigen and help to destroy it
  4. complement cascade
    a complex set of proteins in the bloodstream, that when activated, can facilitate bacterial cell lysis, attraction of WBCs to the site of infection, and stimulation of phagocytosis.
  5. B-cells
    Produces plasma cells and memory cells
  6. macrophages
    phagocytize pathogens and display their antigens
  7. Helper T-cells
    stimulate the proliferation of B-cells and T-cells
  8. T-cells
    produce cytotoxic T-cells and memory cells
  9. Regulatory T-Cells
    Help turn off the immune response when the threat is over
  10. Memory cells
    Remain dormant in the body, in case of future infection
  11. Plasma cells
    produce antibodies
  12. release chemical which causes infected cells to develop holes in their membranes and die
    cytotoxic t-cells
  13. Lymph capillaries
    The smallest lymphatic vessels
  14. The lyphatic vessel that empties directly into the left subclavian vein
    Thoracic duct
  15. Spongy organ located in the left upper quadrant of the abdomen
    Spleen
  16. This organ gets smaller with age, and may even disappear in adults
    Thymus
  17. What is the path that lymph makes through the body?
    • Lymph capillary
    • Lymphatic vessel
    • Lymph trunk
    • Lymphatic duct (right or left)
    • Subclavian vein (right or left)
  18. What chemicals are produced by damaged tissues and WBCs to stimulate immune response?
    • Cytokines
    • cyto - cell
    • kine - movement (kinetic, kinesiology...)
  19. Symptoms including pain, swelling, redness and heat are characteristic of what?
    Inflammation
  20. What is the name of the fluid that bathes cells and is cleaned by the lymphatic system?
    Interstitial or extracellular fluid
  21. What are the molecules on the outer surface of cells that identify them as "friend" or "foe"?
    antigens
  22. These proteins are produced by the body and bind to foreign cells and/or substances
    antibodies
  23. What type of immunity is the body's inborn ability to fight infection?
    innate immunity
  24. What type of immunity targets specific invaders adn is able to "remember" them in case of future invasion?
    adaptive or acquired immunity
  25. what is the complex series of reactions that activate several different pathogen-fighting proteins in the blood?
    complement cascade
  26. what does chemotaxic mean?
    • moving towards chemicals
    • chemo - chemicals
    • taxic - moving towards
  27. which cells are chemotaxic?
    WBCs
  28. lymph node
    filters pathogens out of the blood
  29. spleen
    removes old/damaged RBCs and filters pathogens from the bloodstream
  30. tonsils
    structures in the throat that contain lymphatic tissue
  31. thymus
    secretes a hormone that helps T-Lymphocytes mature
  32. neutrophil
    performs phagocytosis early in infection
  33. basophils and mast cells
    release chemicals like histamine that promote inflammation
  34. macrophages
    perform phagocytosis later in infection and display foreign antigens to stimulate other cells in the immune system
  35. T-lymphocytes
    directly kill infected cells and remember past infections
  36. B-lymphocytes
    release antibodies and remember past infections
  37. Which of the following is not a cell of the innate immune response? neutrophil, macrophage, basophil, b-lymphocyte
    B-lymphocyte
  38. What type of lymphocyte selection occurs when lymphocytes that recognize and bind to the body's own antigens are destroyed?
    Negative lymphocyte selection
  39. A patient receives a vaccination that causes him/her to become immune to a virus, what type of immunity is this and why?
    • Artificial active immunity
    • artificial because it introduces the virus to the body
    • active because it stimulates a response against the virus
  40. HIV decreases the immune function by infecting and destroying what cells?
    Helper T-lymphocytes
  41. What physiological response causes a fever?
    cytokines trigger the hypothalamus to raise the body's temperature
  42. B-cells are responsible for what type of immunity
    antibody-mediated immunity
  43. Cytotoxic T-Cells are responsible for what type of immunity
    cell-mediated immunity
  44. What is active immunity
    when antibodies are produced by your own body
  45. what is passive immunity
    when antibodies are introduced to your body from an outside source
  46. what kind of disorder occurs when a person's immune system attacks his/her own body?
    autoimmune disorder
  47. an allergy can also be called what?
    hypersensitivity
  48. this is a systemic, life-threatening allergic reaction
    anaphylaxis
