  1. CD4
    • one of a group of proteins on the surface of lymphocytes that enhance immune recognition
    • immune cells that express CD4 are known as helper T cells
  2. gamma globulin
  3. immunocompromised
    pertaining to an immune response that has been weakened by a disease or an immunosuppressive agent
  4. immunization
    the protection from specific diseases by vaccination or the injection of immunoglobulins
  5. immunoglobulins
    • antibodies are proteins secreted by B lymphocytes in response to foreign invaders
    • IgM, IgA, IgD, IgD, and IgE
  6. interstitial fluid
    • extracellular fluid that fills the spaces between most of the cells of the body and provides a substantial portion of the liquid environment of the body
    • formed by filtraation through the blood capillaries, it is drained away as lymph
    • closely resembles blood plasma in composition but contains less proteins
  7. Kupffer cells
    • specialized cells of the reticuloendothelial system lining the sinusoids of the liver
    • the function of Kupffer cells is to filter bacteria and other small foreign proteins out of the blood
  8. lysosomes
    • spherical membranous bags containing digestive enzymes that are abundant in phagocytes
    • play an important role in disarming ingested bacteria, viruses, and toxins
  9. macrophage
    • a large phagocyte found in lymph nodes and other tissues of the body
    • major phagocytic cells of the immune system and have the ability to recognize and ingest all foreign antigens
  10. osteoclast
    • a giant multinuclear cell formed in the bone marrow of growing bones
    • found in depressions on the surface of the bone
    • aid in absorbing and removing excess bone tissue in the remodeling of growing bones, or in the repair of damaged or fractured bones
  11. natural killer cell
    • a lymphocyte that is capable of binding to and killing virus-infected and some tumor cells by releasing cytotoxins
    • found in the bone marrow, lymph nodes, and spleen
    • cytotoxic activity is not antibody dependent
  12. pathogen
    any disease-producing agent or microorganism
  13. phagocyte
    a cell (such as leukocyte or macrophage) that has the ability to ingest and destroy particulate substances such as bacteria, protozoa, other cells and cellular debris, dust particles, and colloids
  14. aden/o
  15. adenoid/o
  16. angi/o
  17. agglutin/o
    clumping, gluing
  18. immun/o
    immune, immunity
  19. lymph/o
  20. myel/o
    bone marrow, spinal cord
  21. phag/o
    swallowing, eating
  22. splen/o
  23. adenopathy
    disease of gland
  24. adenoiditis
    inflammation of adenoid tissue
  25. angiopathy
    any disease of blood or lymph vessels
  26. agglutination
    the process of clumping or gluing together
  27. immunogen
    producing immunity
  28. lymphedema
    a swelling of lymph tissue caused by abnormal accumulation of tissue fluid in the interstitial spaces
  29. myeloma
    tumor originating in the bone marrow
  30. splenomegaly
    enlargement of the spleen
  31. tonsill/o
  32. thym/o
    thymus gland
  33. tonsillitis
    inflammation of the tonsils
  34. thymoma
    usually a benign tumor of the thymus gland
  35. -asthenia
    weakness, debility
  36. -blast
    embryonic cell
  37. -cyte
  38. -pathy
  39. -phylaxis
  40. myasthenia
    weakness of muscles and abnormal fatigue
  41. osteoblast
    immature or embryonic bone cell
  42. macrophagocyte
    a large phagocyte
  43. lymphadenopathy
    disease of the lymph glands
  44. anaphylaxis
    • against protection
    • life-threatening hypersensitivity reaction to a previously encountered antigen
