  1. a point on the surface of an organ where blood vessels lymphatic vessels, or nerves enter and leave, usually marked by a depression and slit; the midpoint of the concave surface of any organ that is roughly bean-shaped, such as the lymph nodes, kidneys, and lungs.  Also called:
    Hilum or Hilus
  2. any disease in which antibodies fail to distinguish between foreign and self-antigens and attack the body's own tissues; for example systemic lupus erythematosus and rheumatic fever
    autoimmune disease
  3. a freely movable synovial joint such as the knuckles, elbows, shoulders, or knees
  4. the movement of a cell along chemical concentration gradients, especially the attraction of neutrophils to chemicals released by pathogens or inflamed tissues.
  5. the fluid contained in ymphatic vessels and lymph nodes, produced by the absorption of tissue fluid.
  6. an organ system consisting of lymphatic vessels, lymph nodes, the tonsils, spleen, and thymus; functions include tissue fluid recovery and immunity
    lymphatic system
  7. any interleukin secreted by a lymphocyte
  8. a small organ found along the course of a lymphatic vessel that filters the lymph and contains lymphocytes and macrophages, which respond to antigens int the lymph
    lymph node
  9. a secretion found in tears, milk, saliva, mucous, and other body fluids that destroys bacteria by disrupting their cell walls; variousy regarded as hydrolytic enzymes or as a polysaccharide surfacant.  Also called___
    lysozyme or muramidase
  10. any cell of the body, other than a leukocyte, that is specialized for phagocytosis; usually derived from blood monocytes and often functioning as antigen-presenting cell
  11. any interleukin secreted by a monocyte or macrophage
  12. migration of formed elements of the blood through capillary wall into the interstitial spaces.
  13. any disease-causing organism or chemical
  14. a form of immediate hypersensitivity in which an antigen triggers the release of inflammatory chemicals, causing edema, congestion, hives, and other, usually local, symptoms.
  15. a t lymphocyte that directly attacks and destroys infected body cells, cancerous cells, and the cells of transplanted tissues.
    cytotoxic t cell
  16. a fever-producing agent
  17. a delicate, branching macrophage found in the reticular connective tissue of the lymphatic organs.
    reticular cell
  18. a type of lymphocyte involved in nonspecific defense, humoral immunity, and cellular immunity; occurs in several forms including helper, cytotoxic, and suppressor t cells and natural killer cells.
    t cell
  19. a cell that phagocytizes an antigen and displays fragments of it on it's surface for recognition by other cells of the immune system; chiefly macrophages and b lymphocytes.
    antigen-presenting cells
  20. a class of relatively small agranulocytes with numerous types and roles in nonspecific defense, humoral immunity, and cellular immunity.
  21. genetically engineered bacteria that contains genes from humans or other species and produce proteins that species; used commercially to produce clotting factors, interferon, insulin, and other products.
    transgenic bacteria
  22. a group of conditions that indicate severe immunosuppression related to infection with the human immunodeficiency virus (HIV); typically characterized by a very low t4 lymphocyte cound and high susceptibility to certain forms of cancer and opportunistic infections
    acquired immunodeficiency syndrome
  23. to complete or enhance the structure or function of something else, as in the coordinated action of two different hormones.
  24. the ability to ward off specific infectio or disease, usually as a result of prior exposure and the body's production of antibodies or lymphocytes against a pathogen. compare sesistance
  25. a population of cells that are mitotically descended from the same parent cell and are identical to each other genetically or in other respects
  26. tissue usually composed of more extracellular than cellular volume and usually with a substantial amount of extracellular fiber; forms supportive frameworks and capsules for organs, binds structures together, holds them in place, stores energy, or transports materials.
    connective tissue
  27. any large molecule capable of binding to an antibody and triggering an immune response.
  28. arupture and destruction of a cell by such agents as complement proteins and hypotonic solutions
  29. a protein of the gamma globulin class that reacts with an antigen; found in the blood plasma, in other body fluids, and on the surface of certain leukocytes and their derivitives.
  30. a type of lymphocyte that performs a central coordinating role in humoral and cellular immunity; target of the human immunodeficiency virus
    helper t cell
  31. a virus that infects human helper t cells and causes aids
    human immunodeficiency virus
  32. a comples of tissue responses to trauma or infection serving to ward off a pathogen and initiate tissue repair; recognized by the cardinal signs of redness, heat, swelling, pain, and compromised function
  33. a population of cells, including leukocytes and macrophages, that occur in most organs of the body and protect against foreign organisms, some foreign chemicals, and cancerous or other aberrant host cells
    immune system
  34. a stationary macrophage in the sinusoid of the liver
    kupffer cell
