  1. Lymph
    • Flows through lymphatic vessels
    • fluid lost from blood capularies
    • 3 liters per day
    • water, ions, protiens, and white blood cells
  2. Capillaries
    • endothelium and connective tissue
    • permeable (everywhere besides blood brain barrier)
    • most cells near capullaries
  3. lymphatic Flow
    • lymphatic capularies
    • lymphatic vessels &nodes
    • lymphatic trunks & ducts
    • dump into subclavian veins
  4. Edema
    swelling due to fluid building up
  5. Elephantiasis
    • warms that entering through your feet
    • reproduce
    • fill up your lymphatic system
    • keeping the fluid from getting back yo your heart
  6. Lymph Nodes
    • ball shaped structures
    • occur in groups
    • filter or trap-immune function (pathogens)
    • lymphocytes & macrophages (monocytes)
    • can be infected (painful)
    • spread cancer
  7. lymphatic Organs
    • 1. spleen
    • 2. tonsils
    • 3. thymus
  8. Spleen
    • left side of abdomin
    • filter blood for disease
    • removes and phagocytize olf RBC's
  9. Thymus
    • right above heart, in mediaastium
    • childrean its tissue but turns to fat as it gets older
    • development of t-lymphocytes
  10. Tonsils
    immunity "memory"
  11. Inate
    • serious of mechanisms that respond the same way to a whole bunch of different diseases.
    • will not remember
  12. Adaptive
    responds to a specific pathogen and will remember it
  13. Chemical Mediators
    • mucus
    • can kill pathogens.....good thing
  14. Sebum
    • oil in hair
    • kills pathogens
  15. Lysosomes
    • membrane bound molecule that kills pathogens
    • filled with lysoxymes
  16. Complement
    • compleated froup of chemicals that needs to be triggered
    • create hole in plasma membrane of bacteria
    • allos sodium and water in so bacteria will explode
  17. Interferons
    • produced by cells infected by a virus
    • triggers surrounding cells to produce an antivirul protein
    • prevents the virus from building RNA, DNA, and protien
  18. White Blood Cells
    • phagocytize, engold bacteria
    • neutrophils and macrophages
  19. Natural killer cells
    lymphocytes that kill infected cells
  20. basophils and most cells
    produce histamines (cause swelling)
  21. eosinophiles
    reduce inflammation
  22. Inflammation
    • injury/infection (swollen red)
    • increase blood flow
    • chemical attraction of phogocytic WBC
    • releases complement
    • fibrin, trap infection
  23. Specificity and memory
    attacking specific pathogens and we are remembering them
  24. Antigens
    • mollicule (forigne) on the surface of cells
    • how body remembers pathogens
    • self vs non-self
