  1. LYMPHATIC SYSTEM
    COMPOSED OF LYMPHATIC VESSELS AND LYMPHATIC ORGANS
  2. FUNCTION OF THE LYMPHATIC SYSTEM
    TRANSPORT MATERIALS THAT LEAKED OUT OF BLOOD CAPILLARIES BACK INTO THE CIRCULATORY SYSTEM. DEFENDS HTE BODY AGAINST INFECTION
  3. LYMPHATIC VESSELS
    SIMILAR IN THE STUCTURE WITH VEINS. LARGER VESSELS HAVE VALVES AND MOVEMENT AIDED BY SAME FACTORS THA MOVE BLOOD THROUGH VEINS; VASOCONSTRICTION, RESPIRATORY MOVEMENT AND SKELETAL MUSCLE CONSTRACTION.
  4. LYMPHATIC CAPILLARIES
    SIMILAR TO BLOOD CAPILLARIES BUT CLOSED ENDED AND LOCATED NEAR BLOOD CAPILLARIES.
  5. LACTEAL
    LYMPHATIC CAPILLARIES LOCATED IN THE VILUS OF THE SMALL INTESTINE THAT CARRY AWAY FAT MOLECULES. LYMPHATIC CAPILLARIES MERG TO FORM LARGER LYMPHATIC VESSELS.
  6. LYMPHATIC VESSELS
    MERG TO FORM LARGER LYMPHATIC VESSELS
  7. LYMPHATIC TRUNKS
    LARGER LYMPHATIC VESSELS THAT ARE NAMES ACCORDING TO THEIR LOCATION: THESE DRAIN LYMPH FROM VARIOUS REGIONS OF THE BODY
  8. COLLECTING DUCT
    THE LARGEST OF THE LYMPHATIC VESSELS. THE LARGEST IS THE RIGHT LYMPHATIC DUCT. THE THORACIC DUCT IN THE SMALLEST OF THE TWO DUCTS. THE DUCT EMPTY INTO THE SUBCLAVIAN VEIN
  9. LYMPHATIC PATHWAY
    LYMPHATIC CAPILLARIES--LYMPHATIC VESSELS--LYMPH NODE-- LARGER LYMPHATIC VESSEL---LYMPHATIC TRUNK--LYMPHATIC DUCT--SUBCLAVIAN VEIN
  10. LYMPH
    TISSUE FLUID THAT'S INSIDE THE LYMPHATIC CAPILLARY. OSMATIC PRESSURE FORCES IN THE INTERSTITAL FLUID INTO THE LYMPHIC CAPILLARIES. ANY OBSTRUCTION WITH THE FLOW OF LYMPH RESULTS IN EDEMA
  11. LYMPHATIC ORGAN
    LYMPH NODE
  12. LYMPH NODE
    KIDNEY SHAPED AND LOCATED ON THE PATH OF THE LYMPHATIC VESSEL
  13. CAPSULE (LYMPH NODE STRUCTURE)
    FIBROUS CONNECTION TISSUE THAT SURROUND THE NODE. IT EXTENDS INWARDS TO DIVIDE THE NODE INTO NODULES. NODULES CONTAIN LYMPHOCYTES AND MACROPHAGES
  14. HILUS(LYMPH NODE STRUCTURE)
    INTENED REGION OF THE NODE THROUGH WHICH BLOOD VESSELS, NERVES AND EFFERENT LYMPHATIC VESSEL PASSES THROUGH AFFERENT LYMPHATIC VESSEL.
  15. AFFERENT LYMPHATIC VESSEL
    LOCATED ON THE CONVEXT SIDE OF THE NODE NAD CARRIES LYMPH INTO THE LYMPH NODE
  16. CORTEX(LYMPH NODE STRUCTURE)
    OUTER TISSUE OF THE NODE.
  17. MEDULLA(LYMPH NODE STRUCTURE)
    INNER TISSUE OF THE NODE
  18. SINUS(LYMPH NODE STRUCTURE)
    SPACES WITHIN THE TISSUE THAT CONTAIN LYMPH
  19. LOCATION OF LYMPH NODES
    ALONG THE PATH OF THE LARGER LYMPHATIC VESSELS: AUXILLARY REGION, INGUINAL REGION, CERVICAL REGION, THORACIC LUMBER REGION.
  20. FUNCTIONS OF LYMPH NODE
    FILTERS LYMPH AND ARE CENTERS OF LYPHOCYTE PRODUCTION
  21. THYMUS
    LOCATED BEHIND THE STERNUM. THEY ARE LARGER IN SIZE DURING INFANCY NAD EARLY CHILDHOOD. THEY SHRINK IN SIZE AS WE GET OLDER. THEY SECREAT A HORMONE CALLED THYMOSIN WHICH HELPS IN THE PRODUCTION OF T LYMPHOCYTES (T CELLS). THESE T CELLS LEAVE THE THYMUS TO PROVIDE IMMUNITY
  22. SPLEEN
    RESEMBLE LYMPH NODE BUT LARGER. THE SPLEEN IS THE LARGEST OF THE LYMPHATIC ORGANS. STRUCTURE IS SIMILAR TO LYMPH NODES. SPLEEN FILTERS BLOOD AND REMOVES DAMAGED BLOOD CELLS. SPLEEN ALSO PRODUCE BLOOD CELLS BEFORE BIRTH.
  23. OTHER LYMPHATIC ORGANS
    ADENOIDS, PHARYNGEAL TONSILS AND PEYES PATCHES, LOCATED ON THE ABDOMINAL REGION
  24. BODY DEFENSES AGAINST INFECTION
    PATHOGENS: DISEASE CAUSING AGENTS. EXAMPLES : BACTERIA, VIRUS, PROTOZOA, FUNGI AND PARASITES
  25. 2 LINES OF DEFENSE
    NON-SPECIFIC DEFENSES AND SPECIFIC DEFENSES
  26. NON-SPECIFIC DEFENSES
    GUARD AGAINST MANY TYPES OF ORGANISMS. THEY PROVIDE GENERAL IMMUNITY TO VARIOUS PATHOGENS. THEY WORK TOGETHER TO PROTECT THE BODY FROM INFECTION
  27. SPECIFIC DEFENSES
    GUARD AGAINST VERY SPECIFIC PATHOGEN. CARRIED OUT BY LYMPHOCYTES THAT RECOGNIZE A SPECIFIC INVADER.
  28. NON-SPECIFIC (GENERAL) DEFENSES
    SPECIES RESISTANCE, MECHANICAL BARRIERS,INFLAMMATION,PHAGOCYTOSIS,ANTIGENS,HAPTENS
  29. SPECIES RESISTANCE
    A SPECIES MAY BE RESISTANT TO A DISEASE THAT OTHER SPECIES ARE AFFECTED, BUT MAY BE AFFECTED BY A DISEASE THAT MAY NOT AFTER OTHER SPECIES
  30. MECHANICAL BARRIERS
    UNBROKEN SKIN,MUCOUS MEMBRANE: PREVENT ENTRY OF PATHOGENS
  31. INFLAMMATION
    TISSUE RESPONSE TO A PATHOGEN. SIGNS: SWELLIN,REDNESS,HEAT AND PAIN
  32. PHAGOCYTOSIS
    MOST ACTIVE PHAGOCYTES: NEUTROPHILS,MONOCYTES,MACROPHAGES. THEY REMOVE PATHOGENS FROM THE BODY
  33. ANTIGENS(SPECIFIC DEFENSES)
    PROTEINS AND OTHER LARGE MOLECULES THAT BRING ABOUT AN IMMUNE RESPONSE. A,B AND D ANTIGENS ARE EXAMPLES
  34. HAPTENS
    SMALL MOLECULES THAT ARE NOT ANTIGENIC BY THEMSELVES. WHEN THEY COMBINE WITH OTHER MOLECULES THEY BECOME ANTIGENIC. IN BLOOD, THE PRESCENCE OF ANTIGENS STIMULATE THE PRODUCTION OF ANTIBODIES
  35. LYMPHOCYTE ORIGIN
    • BONE MARROW: AFTER BIRTH
    • SPLEEN, YOLK SAC NAD LIVER BEFORE BIRTH
  36. T CELLS
    LYMPHOCYTES THAT ARE PROCESSED IN THE THYMUS. THEY PROVIDE CELL MEDIATED IMMUNITY. THEY REACT DIRECTLY WITH PATHOGENS.
  37. B CELLS
    LYMPHOCYTES PROCESSED IN THE BONE MARROW. THEY REACT INDIRECTLY TO PATHOGENS NAD BRING ABOUT ANTIBODY MEDIATED IMMUNITY. T CELLS AND B CELLS REACT TOGETHER TO BRING IMMUNE RESPONSE
  38. TYPES OF ANTIBODY: GAMDE
    IgG,IgA,IgM,IgD,IgE
  39. TYPES OF ACQUIRED IMMUNITY
    NATURALLY ACQUIRED ACTIVE IMMUNITY, ARTIFICIALLY ACQUIRED IMMUNITY,NATUALLY ACQUIRED PASSIVE IMMUNITY, ARTIFICIALLY ACQUIRED PASSIVE IMMUNITY
  40. NATURALLY ACQUIRED IMMUNITY
    DEVELOPS WHEN ONE DEVELOPS A DISEASE
  41. ARTIFICIALLY ACQUIRED ACTIVIE IMMUNITY
    DEVELOP WHEN ONE RECEIVES A VACCINE
  42. ARTIFICIALLY ACQUIRED PASSIVE IMMUNITY
    DEVELOPS WHEN ONE GETS A SHOT OF GAMMA GLOBULIN
  43. NATURALLY ACQUIRED PASSIVE IMMUNITY
    DEVELOPS WHEN A BABY RECEIVES THE IMMUNITY FROM THE MOTHER'S MILK OR THE PLACENTA
  44. ACTIVE IMMUNITY
    LASTS LONGER THAN PASSIVE IMMUNITY
  45. HIV
    • HIV stands for Human Immunodeficiency Virus.
    • HIV is a virus.
    • Some viruses, such as the ones that cause the common cold or the flu, stay in the body only for a few days.
    • Some viruses, such as HIV, never go away.
    • When a person becomes infected with HIV, that person becomes "HIV positive" and will always be HIV positive.
    • Over time, HIV disease infects and kills white blood cells called CD4 lymphocytes (or "T cells") and can leave the body unable to fight off certain kinds of infections and cancers.
  46. AIDS
    • AIDS stands for Acquired Immune Deficiency Syndrome
    • caused by HIV.
    • The names HIV and AIDS can be confusing because both terms describe the same disease.
    • Think of AIDS as advanced HIV disease.
    • A person with AIDS has an immune system so weakened by HIV that the person usually becomes sick from one of several opportunistic infections or cancers such as PCP (a type of pneumonia) or KS (Kaposi sarcoma), wasting syndrome (involuntary weight loss), memory impairment, or tuberculosis.
    • If someone with HIV is diagnosed with one of these opportunistic infections (even if the CD4 count is above 200), he or she is said to have AIDS.
    • AIDS usually takes time to develop from the time a person acquires HIV -- usually between 2 to 10 years or more.
  47. CAUSES OF AIDS AND HIV
    • In 1981, the first cases of severe immune system deterioration were recognized when several young men developed unusual infections and cancer.
    • The new disease was later named "AIDS". At that time, no one knew what was causing the disease.
    • Since then, science has shown that the Human Immunodeficiency Virus (HIV) is the cause of AIDS.
    • We know this because people who become infected with the virus can develop AIDS, and medicines that act against the virus can prevent infected people from getting sick.
    • As HIV infection progresses, it weakens a person's ability to fight off diseases.
    • By attacking the immune system, the virus leaves people more susceptible to other diseases.
    • When a person with HIV contracts one of several additional diseases, or when a person's immune system shows marked deterioration, that person is classified as having AIDS.
    • Some individuals and groups have tried to push the false idea that AIDS is not caused by HIV.
    • These claims can be really harmful. If people are led to believe that they do not need to reduce their risk of getting or spreading HIV, they could become infected or pass the virus to others.
    • Also, if people with HIV think they do not need to get medical care or consider treatment, they could become very sick and develop AIDS
  48. PREVENTION
    • Protecting yourself against HIV is about knowledge. Understanding how you get (and avoid getting) HIV, and knowing yourself and your partner (or partners), are key to protecting yourself against HIV.
    • Many people who "know better" engage in risky activities.
    • The reasons for this are numerous and normal: you could be afraid to insist that your partner use a condom; you could make false assumptions about partners (they seem too young, old, healthy-looking, or nice to be HIV positive); you might be a drinker or recreational drug user who does things while under the influence that you wouldn't otherwise consider. T
    • he hardest part of protecting yourself can be learning how to apply what you know to your life and behavior.
    • Be safe and
