5 Matching questions

  1. Formed elements
  2. Hemoglobin Breakdown
  3. Thrombocytopenia
  4. Plasma: Regulatory substances
  5. Eosinophils
  1. a 1. Red blood cells (erythrocytes)
    2. White blood cells (leukocytes)
    3. Platelets (thrombocytes) - ("blood clots") pieces of cells. involved in blood clotting
  2. b 1. RBC life span - 105 to 120 days
    2. Damaged RBCs removed by spleen & liver
    3. Broken down into heme & globin
    4. Globin - amino acids
    5. Heme - (iron mostly)
    a. Biliverdin (green) by product, breaks down bilirubin
    b. Bilirubin (yellow) by product of iron
    Bruise - break down hemoglobin
    spleen - remove any damaged RBCs, WBCs & platelets
  3. c hormones, enzymes
  4. d 1. Leave circulation (blood) and enter tissues during inflammatory response. (get of stuff after allergic response)
    2. Prevalent in allergic reactions.
    3. Destroy inflammatory chemicals like histamine.
    4. Numerous in lining of respiratory and digestive tracts
    5. Account for 2-4% of the WBC.
    6. go after parasitic worms
  5. e too little platelets (bleeding to death)

5 Multiple choice questions

  1. 1. Decreased blood oxygen causes kidneys and liver to release erythropoietin ---> stimulates bone marrow & says make more RBCs (negative feedback loop)
    2. Vitamin B12, folic acid and iron necessary - lack of could cause anemia
    2. kidneys are primary control. how many RBCs there are & they ultimately release erythropoietin. Kidneys measure O2 content
  2. 1. Least common.
    2. Play a role in both inflammatory response & allergic reactions. cause allergic response.
    3. Produce histamine and heparin.
    4. Account for less than 1% of the WBC.
    5. Mast cells - in tissues
  3. 1. Function: Transport of oxygen and carbon dioxide
    2. Biconcave discs (b/c no nucleus)
    3. One-third hemoglobin
    4. Lacks nuclei, mitochondria and ribosomes
    5. can repair itself
    6. not much energy
    7. limited lifespan
    8. carbonic anhydrase can be found in RBC
  4. 1. Molecule that stimulates cells to produce antibodies
    2. on the cell - determine what blood type you are
    Note: antigens is what on test, not agglutinogens
  5. oxygen, carbon dioxide

5 True/False questions

  1. RBC abnormalites: Anemia (3)lack of hemoglobin, lack of RBC, can't carry as much oxygen
    1. Iron Deficiency - most common, not enough Hemoglobin due to lack of iron. Iron effects function of making hemoglobin
    2. Pernicious - lack of Vit. B12, not enough RBCs
    Sickle Cell - destruction of RBCs, cells get trapped in blood vessels & they are broken down, then don't have enough RBCs.


  2. Factors Affecting Coagulation: Factors that promote clotting1. Goal: (1) stop bleeding (2) prevent blood loss
    2. Requires platelets and plasma proteins
    3. Require calcium ions as cofactors


  3. Composition of BloodLiquid matrix
    1. Plasma (55%)
    2. Formed elements (45%)
    a. Red blood cells
    b. White blood cells
    c. Platelets
    3. Adults have 4-6 L of blood


  4. White Blood Cell Counts1. cells become thin, elongate and move either between or through endothelial cells of capillaries
    2. migrate out of blood vessels and into tissue spaces.


  5. White Blood Cells: Chemotaxis1. cells become thin, elongate and move either between or through endothelial cells of capillaries
    2. migrate out of blood vessels and into tissue spaces.
