  1. PCV
    percentage of erythrocytes (RBC) to the total volume of blood
  2. PCV dog
    40-45
  3. PCV higher than normal
    dehydrated or shock
  4. PCV lower than normal
    lack of RBC=lack of ability to carry oxygen
  5. definition of hematology
    study of iron, hemoglobin, blood
  6. blood is made of two portions:
    • cellular
    • fluid (plasma)
  7. cellular portion of blood:
    • erythrocytes (RBC)
    • leukocytes (WBC)
    • thrombocytes (platelets)
  8. fluid (plasma) portion of blood:
    • water
    • electrolytes
  9. which are larger, RBC or WBC?
    WBC
  10. dog's average RBC&WBC per mL
    • RBC-6,000,000-7,000,000
    • WBC-10,000-12,000
  11. 6 major electrolytes
    • Sodium (Na+)
    • Chloride (Cl-)
    • Potassium (K+)
    • Calcium (Ca++)
    • Phosphate (PO4+)
    • Magnesium (Mg++)
  12. saline=
    salt (Na+Cl-)
  13. why are LRS better for the body?
    added electrolytes 
  14. deficiency of the electrolyte Potassium will lead to 
    renal failure
  15. deficiency of the electrolyte Calcium will lead to
    tetany
  16. deficiency of these two electrolytes will kill
    Potassium and Calcium
  17. source of food
    glucose
  18. every single cell participates in this or they are dead
    cellular respiration
  19. pale
    not enough hemoglobin in the RBC
  20. pancreas main job
    produce digestive enzymes

    • 1. amylase
    • 2. lipase
    • 3. trypsin 
  21. insulin
    allows the glucose in the bloodstream to enter cells
  22. high blood glucose=
    • diabetes
    • not enough insulin to allow glucose to get out of the bloodstream and into the cells
  23. major uses for proteins
    • 1.enzymes
    • 2.antibodies
    • 3.muscle
    • 4.plasma membrane
    • 5.hormones
  24. animal in shock, check:
    • heartbeat
    • breathing
    • kidney function (catheterize to see if urine is being produced)

    give fluids to increase BP to make sure toxins are able to be filtered out of the body
  25. part of kidney that filters toxins from the blood
    glomerulus
  26. #1 toxin
    urea
  27. *shock*
    the movement of blood from peripheral circulation to internal circulation
  28. variation in size of RBC
    anisocytosis
  29. anisocytosis
    variation in size of RBC
  30. polychromasia
    many colors
  31. reitculocyte
    • immature RBC
    • causes anisocytosis &/or polychromasia
  32. poikilocytosis
    abnormal shape
  33. abnormal shape
    poikilocytosis
  34. stacked RBC

    • 2. blueish cytoplasm
    • 3. vacuoles in cytoplasm
    • 4. indented nucleus
  36. crenation
    projections on RBC

    caused by rough handling or staining slide before blood is dry
  37. dacrocyte

  39. keratocyte
    RBC with a bite taken out
  40. schistocyte
