1. garlic
    (allicin) a phytochemical that may lower cholestol and make platelets less adhesive.
  2. salmon
    fresh or canned is one of the best sources of Omega-3 fatty acids which aids in heart health and help with arthritis.
  3. tomatoes
    lycopene can aid in lowering the risks for some cancers and heart disease.
  4. structures of the immune system
    • *thymus(wbc)
    • *spleen (LUQ)(live w/or w/o)
    • *lymph system (continous flushing)
    • *bone marrow
    • *WBC (Fixed,organ. Wondering, looking for problem)
    • *antibodies(disease fighting protein)
    • *complement system
    • *hormones
  5. intact skin
    an important part of the immune system. It acts as a primary boundary between germs and your body.
  6. skin
    tough and generally impermeable to bacteria and viruses.
  7. respiratory system
    nose, mouth, and eyes are obvious entry points for germs.
  8. Whats found in tears and mucus that brakes down the cell wall of many bacteria?
    tears and mucus contains an enzyme(lysozyme) that brakes down the cell wall of many bacteria.
  9. B Cells
    • ( B lymphocytes)
    • *When stimulated, mature into plasma cells, these are the cells that produce antibodies.
    • *Produce memory and antibodies.
    • *start in the marrow but migrate thru the blood stream to the thymus and mature there;because of exposure to the hormone thymosin, which is secreted by the thymus.
  10. B Cell
    identifies a specific germ, and when the germ is present in the body the B cell clones itself and produces millions of antibodies designed to eliminate the germs.
  11. T Cells
    • *all T Cells have CD3 ( cluster of designation) receptor complexes and various other CD antigens.
    • *destroy cells containing the antigen they are specific for.
  12. Cytotoxic T-Cells
    • very aggressive WBC.
    • once activated, cytotoxic T-Cell (TC-Cell) begin dividing to produce more TC-Cells, and TC-memory cells.
  13. suppressor T-Cells
    • (TS-Cells)
    • produce inhibitory cytokines for T-Cells and B-Cells.
    • keeps homeostasous stable.
  14. antigen
    (non self) foreign to the body (varicella, tetanus, HIV, HBV, influenza, streptococci).
  15. antibody
    disease fighting protein produced by the immune system form the presence of a specific antigen.
  16. antigen-antibody reaction
    binding of antigens and antibodies to complexes.
  17. immunoglobulins (antibodies)
    • *IgG most abundant of the antibodies and are found in the blood serum and lymph. Fight against antigens.
    • *IgA fights agianst ingested antigens and are found in saliva, sweat, or tears.
    • *IgM first antibodies to appear in responce to initial exposure to an antigen.
  18. active immunity
    vaccines are used for health purposes to expose our bodies to a particular antigen.(tetnus, immunacation shots).
  19. passive immunity
    acquired naturally happens when a mother transfer antibodies to her offspring via placental route during pregnancy and colostrum during breastfeeding.
  20. aquired immunity
    • *is not present at birth, it is learned.
    • *as a person's immune system encounters foreign substances(antigens) the components of acquied immunity learn the best way to attack each antigen and begin to develope a memory for that antigen.
    • *aka specific immunity because it tailors its attack to a specific antigen previously encountered.
  21. lymph nodes
    • (bean shape)(stationary tissue) contains specialized lymphocytes that are capable of destroying pathogens.
    • -range in size from a few millimeters to about 1-2cm in there normal state.
    • *500-600 lymph nodes thru out your body.
  22. spleen
    • major filtration for the blood.
    • (LUQ) of the abdomen and is to the left of the stomach.
  23. appendix
    is a 3 1/2in long tube of tissue that extends from the large intestine.
  24. thymus
    • *prepares the leukocytes for battle with the maturation process of them into T-Cells.
    • *superior to the heart,composed largly made of lymphoid tissue, is an endocrine gland that assists the immune system.
    • *the thymus that lymphocytes mature, multiply, and become T-cells (T for Thymus).
    • *Tcell maturation is regulated by hormones produced by the thymus, including thymopoietin and thymosin.
  25. peyer's patches
    • these are lymphoid follicles similar in many ways to lymph nodes. B-Cells are present and help us defend the body.
    • *collection of large oval lymph tissues that are located in the mucus-secreting lining of the human small intestine.
    • *lymph nodules located walls of ileum, small intestine.
    • *named for the seventeenth century Swiss anatomist, Hans Conrad Peyer.
    • *30-40 patches or bundles in an individuals intestine.
    • *high concentration of wbc that help protect the body from infections and diseases.
    • *detect antigens such as bacteria and toxins. Bcells go to wk.
  26. lymph nodes
    • *filter fluids, catching viruses, bacteria and other unknown materials. thenyour unique WBC destroy the unwanted materials.
    • *approximately 500-600 lymph nodes thru out your body.
  27. ruptured appendix
    will be preceded by extreme abdominal pain that often starts near the belly button and then migrates to the lower right portion of the abdomen.
  28. structures of the lymphatic system
    • lymph
    • lymphatic vessels
    • ducts
    • lymph nodes
    • additional:
    • tonsils
    • thymus
    • spleen
    • lacteals
    • peyers patches
    • vermiform appendix
    • lymphocytes(wbc)
  29. natural immunity
    passed thru mother to her fetus( developing child) before birth. Last only short time.
