  1. what are the two main componants of blood
    • formed elements 
    • plasma
  2. what are the formed elements made up of
    • red blood cells
    • white blood cells
    • platelets
  3. what is the function of a red blood cell
    transports oxygen and helps to transport carbon dioxide
  4. what is the function of a white blood cell
    defense and immunity
  5. what are the function of platelets
    blood clotting
  6. what is plasma made up of
    • water 
    • electrolytes
    • proteins
    • wastes
    • vitamins
    • hormones
  7. what is the function of water in the blood
    solvent for carrying other substances
  8. what are the functions of electrolytes
    • osmotic balance
    • pH buffering
    • regulation of membrane permeability
  9. what is the funciton of proteins in the blood
    • osmotic balance
    • pH buffering
    • clotting
    • immunity
  10. what are the four steps of red blood cell production
    • O2 level drops
    • sensor causes kidneys to release EPO 
    • EPO causes rbc production increase which picks up more oxygen
    • oxygen levels get high enough kidneys recognize increase in oxygen and stop EPO release.
  11. what are two steps of rbc destruction
    • rbc gets old or damaged and cannot repair
    • spleen starts using macrophages that will break apart the rbc and recycle the parts
  12. what is a normal hematocrit
    • men 4,600,000-6,200,000
    • women 4,200,00-5,400,000
  13. what is a normal white blood cell count
    4,000-11,000
  14. what is a normal t-cell count
    800-1,000
  15. what are some disease that cause an incease in white cell count
    • leukocytosis
    • severe infection(appendicitis)
    • cancers like leukemia
  16. what are some diseases that cause a decrease in white cell count
    • leukopenia
    • aids
    • influenza
    • chicken pox
  17. what stimulates white blood cell production
    • activitated T-cells (interleukins)
    • colony stimulating factors
  18. not enough rbc or hemoglobin and caused by not enough iron needed to make hemoglobin
    anemia
  19. to many rbc
    plycythemia
  20. decrease in white blood cells. less than 4,000
    leukopenia
  21. increase in white blood cells. more than 11,000
    leukocytosis
  22. part of an immune response and are some of the first cells at the sight of injury/infections
    neutrophils
  23. part of immune response that split into dendritic cells and macrophages
    monocytes
  24. defender cells that remember the invaders to make you immune
    t-cells
  25. specialized defender cells that remember invaders
    type of agranulocyte that makes anti bodies
    b cells
  26. release a lot of heprin amd histamine(degranulation) which causes vasodilation
    basophils
  27. release heprin and some histamine. kills parasites
    eosinophils
  28. what are the steps for blood clot formation
    • damage tissue releases thromboplastin
    • thromboplastin initiates reaction that results in the production of prothrombin activator
    • prothrombin activator turms prothrombin to thrombin
    • thrombins catalyze reaction that joins fragments of fibrinogen into fibrin
    • fibrin sticks to damaged vessels to form a clot
  29. initial cut causes vessel to contract
    vasospasm
  30. platelets adhere to rough surface and each other to form a plug to stop bleeding
    platelet plug
  31. the formation of a blood clot
    coagulation
