The flashcards below were created by user teriann on FreezingBlue Flashcards. What would you like to do?


  1. phagocytosis
    ingesting and digesting pathogens and foreign objects by phagocytes
  2. Lysis
    to break down or destroy
  3. Erythema
    redness of the skin
  4. Sepsis
    Dangerous infection of the blood stream
  5. Functions of the Lymphatic/Immune Systems
    • - Fight diseas and infection
    • - Maintains fluid and protein balance
    • - Aids in digestion
  6. Chacteristics of Lymph:
    • - plasma portion of blood leaked from caps
    • - 90% back to heart, 10% into tissue as interstitial fluid
    • - delivers oxygen, glucose, and hormones to cells
    • - carries proteins and waste as it leaves cells
    • - carries lipids from digestive tract, milky color
    • - after being filtered by lymph nodes, lymph carries high WBCs
  7. Organs of the Lymph System:
    • Bone Marrow
    • Thymus
    • Lymph nodes
    • Spleen
    • Tonsils & Adenoids
  8. Lymph Vessels
    • - like blood vessels, have valves like veins and return fluid to heart
    • - unlike blood vessels:
    •  - One way, to the heart
    •  - lymph circulation does not have pump
    •  - found in most parts of body, except the bone marrow, cns, and epidermis
  9. lymph capillaries
    collect fluid from head and feet and move toward neck
  10. lymph nodes:
    filter lymph and remove bacteria and foreign substances
  11. Antigens:
    protein molecules found on the surface of the cell membranes

    help identify what belongs to the body and what does not
  12. Cytokines:
    Neutralize invaders that cross the immune system barrier

    • - interferon
    • - TNF, tumor necrosis factor
    • - Interleukins
    • - Complement cascade
  13. Antibodies/Immunoglobulins
    Identify and neutralize foreign substances, produced by a type of B cells, plasma cells
  14. WBC Neutrophils
    • - engulf and remove pathogens (phagocytes)
    • - signal immune response
    • - most numerous
    • - first to arrive
    • - innate immunity
  15. WBC Basophils:
    • - release chemicals to promote inflammation
    • - low in number
    • - arrive from the blood
    • - innate immunity
  16. WBC Mast Cells:
    • - release histamines to promote inflammation
    • - not mobile- stationed in connective tissue
    • - innate immunity
  17. WBC eosinophils
    • - manage response of basophils and mast cells
    • - fight parasitic invasions and allergens
    • - low in number
    • - innate immunity
  18. Macrophages:
    Assist in tissue repair
  19. Natural Killer (NK) cells:
    provide immunity against virus and tumors
  20. T-lymphocytes
    T-cells
    Kill infected cells, remember pathogens
  21. B-lymphocytes
    B-cells
    Plasma cells, produce antibodies, stored in lymph nodes
  22. Innate Immunity:
    • - First line of defense
    • - cells are directly responsible for destruction of non-antigens
    • - reacts immediately
    • - reacts to a variety of antigens, destroys anything that is a non-self antigen
    • - does not have memory of prior exposure with antigens
  23. Adaptive Immunity
    • - second line of defense
    • - antibodies (not cells) are responsible for destruction of non-antigens
    • - takes longer to react
    • - reacts to a specific antigen
    • - has memory from prior exposure to antigens
  24. Circulation of Lymphatic Fluid:
    Blood to tissue to lymphatic capillaries to lymphatic vessels to lymph nodes...to lymphatic vessels to lymphatic trunks to lymphatic ducts to subclavian veins back to blood
  25. antigen
    molecules on the outer surface of a cell used to identify them
  26. antibodies
    proteins that bind to antigens, eventually leading to their destuction
