  1. the disease process that occurs following infection with the human immunodefieciency virus (HIV)
    acquired immune deficiency syndrome (AIDS)
  2. a naturally occurring hormone that also may be given as a cardiac drug and has alpha and beta effects. Also called epinephrine
    adrenaline
  3. a severe reaction to an antigen that occurs after sensitization from a prior exposure to the same antigen
    anaphylaxis
  4. one of two types of specific immunity that wxist in the body, it is primarily mediated by B cells.
    antibody-mediated (humoral) immunity
  5. a substance foriegn to the body
    antigen
  6. a large collection of lymph nodes located in the axilla
    axillary nodes
  7. a white blood cell that may play a role following infection of various areas in the body
    basophil
  8. a protein found on the surface of T helper cells that is adversely affected by exposure to HIV
    CD4 antigen
  9. one of two types of specific immunity that exist in the body, it is primarily mediated by T cells
    cell-mediated immunity
  10. a large collection of lymph nodes located in the neck
    cervical nodes
  11. the process of the migration of leukocytes in the blood toward the areas of bacterial invasion, foreign body, or infection
    chemotaxis
  12. tissue with no clear boundary that blends with surrounding tissues and contains lymphocytes and other cells

  13. escherichia coli, a normal flora or bacteria found in the gastrointestinal tract that aids in digestion and absorption of food, as well as metabolization of waste productss
    e coli
  14. a leukocyte that may play a role following infection in various areas in the body
    eosinophil
  15. a condition that is potentially fatal to a fetus that occurs during late pregnancy or delivery when an Rh negative mother is exposed to small amount of Rh positive fetal blood. Antibodies to Rh antigens may be produced by the mother and enter the fetal circulation and destroy the fetus' red blood cells
    erythroblastosis fetalis
  16. a small molecule that will not evoke a specific immune response unless it is combined with other serum proteins, in which case, a severe reaction may occur
    hapten
  17. a virus that adversely affects a protein on T helper cells, the CD4 antigen, by causing it to appear as an antigen to healthy cells, resulting in destruction of T helper cells and the inability to fight infections and certain types of tumors
    human immunodeficiency virus (HIV)
  18. the body system that is responsible for providing immunity
    immune system
  19. the body's ability to resist damage from foreign substances, microscopic organisms, or harmful chemicals
    immunity
  20. a disease that may be transmitted from one person to another via some type of specific microscopic organism, such as a bacteria or virus
    infectious disease
  21. a response of the immune system that results in the influx of cells and other chemicals to fight a foreign challenge
    inflammatory repsonse
  22. a large collection of lymph nodes located in the groin
    inguinal nodes
  23. one of three sets of lymphatic organs that comprise the tonsils, they are located on the posterior margin of the tongue and help protect the body from bacteria introduced into the mouth and nose
    lingual tonsils
  24. a thin plasma-like liquid fromed from interstitial or extracellular fluid that bathes the tissues of the body
    lymph
  25. round or bean-shaped structures interspersed along the course of the lymph vessels, which filter the lymph and serve as a source of lymphocytes
    lymph nodes
  26. tissue that is denser than diffuse lymphatic tissue, found in the loose connective tissue of the digestive, respiratory, and urinary systems
    lymph nodules
  27. thin-walled vessels through which lymph circulates through the body, they travel close to the major arteries and veins
    lymph vessels
  28. inflammation fo a lymph node caused by infection
    lymphadenitis
  29. any swelling of the lymph nodes, with or without pain
    lymphadenopathy
  30. an infection that spreads beyond the local area into a lymphatic vessel causing red streaks to run from the infected area proximally
    lymphangitis
  31. vessels of the lymphatic system that carry fluid away from the tissues
    lymphatic capillaries
  32. one of two great lymph vessels, it empties into the subclavian vein
    lymphatic duct
  33. a passive circulatory system that transports a plasma-like liquid called lymph, a thin fluid that bathes the tissues of the body
    lymphatic system
  34. a type of white blood cell that helps fight infection and provide immunity
    lymphocytes
  35. complex proteins produced by T effector cells that recruit mast cells and other nonspecific inflammatory mediators to aid in destruction of antigens
    lymphokines
  36. the breakdown of a foreign cell caused, in some cases, when T effector cells bind to the foreign cell
    lysis
  37. cells that leave the bloodstream and enter diseased tissues after the neutrophils and are responsible for the later stages of fighting infection, including the disposal of dead bacteria
    macrophages
  38. a large white blood cell that mediates allergic reactions and may play a role following infection of various areas of the body
    mast cell
  39. the spreading of a disease from one part of the body to another, especially with may forms of cancer
    metastasize
  40. an organism of microscopic size
    microorganism
  41. usually the first cells to enter infected tissues, they ingest bacteria through phagocytosis
    neutrophils
  42. an immune response that is predictable each time the body is exposed to a particular challenge
    nonspecific immunity
  43. bacteria found in certain sites in the body, such as the gastrointestinal tract and oral and nasal cavities that help maintain homeostasis
    normal flora
  44. one of three sets of lymphatic organs that comprise the tonsils, they are located in the back of the throat, on each side of the posterior opening of the oral cavity, and help protect the body from bacteria introduced into the mouth and nose
