  1. AUTOIMMUNE SYSTEM
    WHEN THE IMMUNE SYSTEM MISTAKES SELF FOR NON SELF AND ATTACKS, SUCH AS RHEUMATOID ARTHRITIS
  2. 3 LINES OF DEFENSE OF THE IMMUNE SYSTEM
    • 1. ANATOMIC BARRIERS (SKIN AND MUCOUS MEMBRANES)
    • 2. BIOCHEMICAL BARRIERS (TEARS, PERSPIRATION)
    • 3. MECHANICAL BARRIERS TO ELIMINATE SUBSTANCES(SKIN SLOUGHS OFF, COUGHING)
  3. LYMPHOCYTE
    DEVELOPS FROM A STEM CELL INTO TWO MAJOR CLASSES....B CELLS THAT MATURE IN BONE MARROW AND T CELLS TAHT MATURE IN THE THYMUS.
  4. MONOCYTES
    DEVELOPE FROM THE PHAGOCYTE STEM CELLS. IMMATURE CELLS THAT HAVE LITTLE ABILITY TO FIGHT INFECTION, HOWEVER THEY SWELL AND BECOME MACROPHAGES AND ARE THEN VERY AFFECTIVE.
  5. MACROPHAGES
    THE MOST IMPORTANT FUNCTION IS TO DESTROY ANTIGENS
  6. PHAGOCYTES
    PRODUCED IN LARGE AMOUNTS IN RESPONSE TO PARASITIC INFECTIONS.
  7. BASOPHILS
    RELEASE HEPARIN AND HISTAMINE, WHICH ARE ESSENTIAL COMPONENTS OF THE INFLAMATION PROCESS.
  8. ORGANS OF IMMUNE SYSTEM:
    ARE WHERE THE LYMPHOCYTES DEVELOP.

    • 1. BONE MARROW
    • 2. THYMUS (BY STERNUM)
    • 3. LYMPH NODES (BY GROIN)
    • 4. SPLEEN (BY RIGHT RIBS)
    • 5. TONSILS
    • 6. ADENOIDS
    • 7. APPENDIX
    • 8. PEYERS PATCHES (LYMPOID TISSUE IN SMALL INTESTINE)
  9. LYMPH NODES
    FUNCTION LIKE A FILTER
  10. T LYMPHOCYTES
    PRESENT IN FOUR IDENTIFIABLE TYPES:

    • 1. T CELLS
    • 2. SUPPRESSOR T CELLS
    • 3. MEMORY T CELLS
    • 4. KILLER T CELLS
  11. B LYMPHOCYTES
    THEY ACT UPON THEIR TARGES BY PRODUCING ANTIBODIES.
  12. IMMUNOGLOBULINS
    WHAT GIVES THE B CELL THE ANTIBODY (PROTEIN SUBSTANCE)

    • IGA - CONCENTRATED ON BODY FLUIDS, TEARS, SALIVA..ETC.)
    • IGD - LOCATED ON B CELL MEMBRANES
    • IGE - VERY EFFECTIVE AGAINST PARASITES AND ALLERGIES
    • IGG - THE MOST PLENTIFUL ANTIBODY
    • IGM - FOUND IN BLOODSTREAM AND VERY EFFECTIVE IN KILLING BACTERIA
  13. CYTOKINES
    NONANTIBODY PROTEINS THAT REGULATE THE IMMUNE RESPONSE
  14. INTERFERONS
    PRODUCED BY T CELLS, A FAMILY OF PROTEINS THAT CAN FIGHT VIRUSES.
  15. NK (NON KILLER CELLS)
    NUMEROUS IN THE BLOODSTREAM. KILL CANCER CELLS AND CELLS INFECTED WITH VIRUSES WITHOUT USING ANTIBODIES.
  16. THE IMMUNE SYSTEM HAS TWO BRANCHES.
    ONE FROM THE B CELL ACTIVITY AND ONE FROM THE T CELL ACTIVITY
  17. PSYCHONEUROIMMUNOLOGY
    A NEW SCIENCE TO HELP FIND THE CONNECTION BETWEEN THE BRAIN, BEHAVIOR AND IMMUNITY.
  18. AIDS
    THE VIRUS INVADES THE HELPER T CELLS AND MACHROPHAGES. THIS THROWS OFF THE CYCLE OF THE WHOLE IMMUNE SYSTEM.
  19. CANCER
    GROWTH OF ABNORMAL CELLS. THESE CELLS ACCUMULATE AND FORM TUMORS THAT INVADE OR DETROY NORMAL TISSUE.
  20. METASTASIS
    THE SPREAD OF A TUMOR TO A NEW SITE
  21. NEOPLASM
    NEW GROWTH (SUCH AS IN CANCER)
  22. CANCER ARISING FROM EPITHELIAL TISSUES ARE CALLED?
    CARCINOMAS
  23. CANCERS ARISING FROM CONNECTIVE TISSUES ARE CALLED?
    SARCOMAS
  24. MOST COMMON CANCER IN MEN AND WOMAN
    LUNG / BRONCHUS CANCER
  25. MUTATION OR ABNORMAL ACTIVATION OF CELLULAR GENES THAT CONTROL CELL GROWTH CAUSES:
    CANCER
  26. ONCOGENES
    THE ABNORMAL GENES THAT CONTROL CELL GROWTH AND DIVISION
  27. CARCINOGENS
    CHEMICAL, PHYSICAL OR BIOLOGIC FACTOR IN CAUSING CANCER, SUCH AS ARSENIC, CIGERETTES..ETC.
  28. LUPUS ERYTHEMATOSUS
    CHRONIC DISEASE WHICH CAUSES CHANGES IN THE IMMUNE SYSTEM. CAUSES INFLAMMATION OF VARIOUS PARTS OF THE BODY.

    FEVER, WEIGHT LOSS, HEADACHE, FATIGUE, HAIR LOSS, EDEMA, VOMITING
  29. LYMPHEDEMA
    • SWELLING IN THE TISSUES OF THE BODY CAUSED BY AN ACCUMULATION OF LYMPHATIC FLUID.
    • SWELLING WITHIN THE FATTY TISSUE JUST UNDER TEH SKIN OF THE ARM AND HAND
  30. RHEUMATOID ARTHRITIS
    CHRONIC INFLAMMATORY AUTOIMMUNE DISEASE. AFFECTS JOINTS AND SURROUNDING MUSCLES, TENDONS, LIGAMENTS AND BLOOD VESSELS.
