  1. lymphatic cells
    floating around the body to see if we have any invaders
  2. lymph nodes are
    holding space for the invaders
  3. Invaders are
    bacteria, virus, fungus
  4. why do do we get invaded.
    because our body is warm, dark and moist
  5. Promote growth and development of lymphocytes
    bone marrow,lymph nodes,lymphatic vessels, thymus, spleen, tonsils, appendix, blood(transports)
  6. bone marrow does
    creates cells
  7. Lymph nodes do
    hold lymph cells and invaders
  8. Lymphatic vessels do what
    passageways for lmphatic fluid
  9. What is Major Histocompatibility Complex (MHC)
    • It is in each in every one of your cells
    • -Individual DNA marking in cells
    • -Allows cell to recognize and communicate with each other
    • - Allows cells to recognize any cells with our markings
    • - Creates your immunities
  10. *The invaders cannot communicate with you that’s how they know they are a invader. Our cells can only speak a certain language…. They attack them and Then they take em to the the lymph nodes. The lymph nodes swell because they r filling up with the invaders.They swell in the area where the infection is. Then they get all types of information to kill em.
    Purpose of MHC
  11. What is able to remember encounters with foreign cells and record how to respond
    immune cells
  12. Types of lymphatic cells
    lymphocytes,bcells, t cells
  13. lymphcytes are
    white blood cells
  14. formed from stem cells and hold the antibody markers for future encounters with invaders (they actually make your antibody)
    Will divide to create “clone” antibody cells
    b cells
  15. directly interacts with unwanted cells
    -Assists with cellular immunity
    t cells
  16. helper t cells
    they activate b cells
  17. attacks infected and malignant cells
    Cytotoxic T
  18. what is da disease that now works with the body
  19. types of lymphatic cells
    intergeron, natural killers (nk), cytokines
  20. intergeron
    fights viruses
  21. natural killers (NK)
    type of lymphocytes that targets tumors and contain deadly chemicals
  22. cytokines
    – regulate immune response -Encourage cell growth -Gathers info from other cells
  23. The greatest concentration of lymph nodes are where
    in the openings of your body
  24. allows fluid to enter the lymph node
    afferent lymphatic vessel
  25. – exit the lymph node
    Efferent lymhatic vessel
  26. Immunoglobins are called
  27. that enter lymph nodes to “ remember” invaders and response
    antibody compley cells
  28. – guards the entrances of the body ( anus, penus, vagina, ears, nose, eyes,mouth)
  29. IgD
    regulates cell activities
  30. IgE
    triggers allergic response
  31. IgG
    coats organisms to speed up immune response
  32. IgM
    kills bacteria
  33. immune response
    an invasion
  34. Recognition of the invador
    Growth of defenses
    Attack of invaders
    Decrease immune response after death of invader
  35. (sensitivity) to substances in your environment – pollen, cat hair
    allergic responses
  36. -Hypersensitivities to environment
    -igE is triggered
    -effects skin, lungs and nasal
    allergic response
  37. actual invasion to your body
    pathogen responses
  38. two types of immunity
    artificially acquired and naturally acquired
  39. immunity after shots given
    Vaccines – cause the porduction of antigen antibody complex and memory cells
    Ready made antibodies – temporary treatment used to prevent diseases
    artificially acquired
  40. immunity after contracting disease
    Active Immunity – a result of infection
    Congenital immunity – immunity passed from mother to fetus or mother to infant through breast milk temporary immunity
    naturally aquired
