  1. purpose of lymphatic cells
    fto protect the body from invaders, to promote growth & development of lymphocytes
  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, helper t, cytotoxic t, interferon, natural killers (nk), cytokines
  13. lymphoytes 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. interferon
    fights viruses
  20. natural killers (NK)
    type of lymphocytes that targets tumors and contain deadly chemicals
  21. cytokines
    – regulate immune response -Encourage cell growth -Gathers info from other cells
  22. The greatest concentration of lymph nodes are where
    in the openings of your body
  23. allows fluid to enter the lymph node
    afferent lymphatic vessel
  24. – exit the lymph node
    Efferent lymhatic vessel
  25. Immunoglobins are called
  26. that enter lymph nodes to “ remember” invaders and response
    antibody compley cells
  27. – guards the entrances of the body ( anus, penus, vagina, ears, nose, eyes,mouth)
  28. IgD
    regulates cell activities
  29. IgE
    triggers allergic response
  30. IgG
    coats organisms to speed up immune response
  31. IgM
    kills bacteria
  32. immune response
    an invasion
  33. Recognition of the invador
    Growth of defenses
    Attack of invaders
    Decrease immune response after death of invader
  34. (sensitivity) to substances in your environment – pollen, cat hair
    allergic responses
  35. -Hypersensitivities to environment
    -igE is triggered
    -effects skin, lungs and nasal
    allergic response
  36. actual invasion to your body
    pathogen responses
  37. two types of immunity
    artificially acquired and naturally acquired
  38. 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
  39. 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
  40. stage of infectious disease 1
    Incubation Stage – the time between exposure to a pathagon and the signs and symptoms appearing in the body.(when u are more contagious)
  41. stage of infectious disease 2
    Prodromal Stage: the beginning stage of the active disease
  42. stage of infectious disease 3
    Acute Stage – disease reaches its peak(highest point) in the body(you are the sickest) the pathogen is at its strongest
  43. stage of infectious disease 4
    Declining Stage- signs and symptoms begin to fade
  44. stage of infectious disease 5
    Convalescent Stage – the patient is recovering
  45. How do u help keep your family healthy when one person is sick.?
    Quarentine, washing sheets, throw away trash, spray lysol and clean with bleach
  46. Barriers –
    physical protection from microbes - Skin --Mucus membrane -Bodily secretions
  47. any protection from attacks from viruses, fungi but does not produce immunities
    Cell mediated immunity
  48. produces antibodies that are capable of killing micrrobes and recognizing pathogens again.
    Humoral immunity
  49. Human Immunodefieciency Virus HIV –
    the virus that causes AIDS. Kills our B and T cells
  50. Sanitation –
    washing of items to remove it dirt and debris
  51. the process of cleaning instruments and work areas using chemicals that destroy some microorganism.
  52. any process that kills all microorganism

    High pressure
