5 Matching questions

  1. Hematocrit
  2. Basophils
  3. functions of blood
  4. ABO Blood Groups: Type AB
  5. Platelets
  1. a 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
  2. b 1. Percent of blood (volume) that is RBCs - by centrifruge
    2. Indicates problem but not what problem is
    3. Normal 38-45%
  3. c 1. Transportation of dissolved gases, nutrients, hormones, and metabolic wastes. (by dissolved or a carrier molecule)
    2. Regulation of the pH and ion composition of interstitial fluids. (HOMEOSTASIS)
    3. Restriction of fluid losses at injury sites. (blood clots)
    4. Defense against toxins and pathogens. (WBCs)
    5. Stabilization of body temperature.
  4. d Type AB
    Both antigen A and antigen B on RBC
    No antibody in serum
  5. e three characteristics
    1. Adhesive - stickey
    2. Aggregate - platelets come together
    3. Agglutination - large amount clump together, it's NOT a clump
    4. Pinched off of megakaryocyte
    5. Thrombocytopenia - too little platelets (bleeding to death)
    6. Thrombocytosis - too many platelets (too much clotting)

5 Multiple choice questions

  1. 1. Goal: (1) stop bleeding (2) prevent blood loss
    2. Requires platelets and plasma proteins
    3. Require calcium ions as cofactors
  2. 1. A network of threadlike fibrin fibers, trapped blood cells, platelets and fluid
    2. Clot retraction. Fibrin threads of clot attached to blood vessel walls.
    a. Platelets produce processes that attach to fibrin threads.
    b. Actin and myosin molecules within platelets contract, pulling edges of wound together and squeezing out serum.
  3. 1. Arrest of bleeding
    2. Events preventing excessive blood loss
    a. Vascular spasm: Vasoconstriction of damaged blood vessels.
    b. Platelet plug formation
    c. Coagulation or blood clotting
  4. 1. Based on genetics
    2. Four types: A, B, AB & O

    3. Agglutination: clumping of red blood cells in response to a reaction between an antibody and an antigen
  5. Mobile clot

5 True/False questions

  1. Red Blood Cells (Erythrocytes)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

          

  2. Plasma: ProteinsProteins:
    1. Albumins: viscosity, osmotic pressure, buffer, transports fatty acids, free bilirubin, thyroid hormones
    2. Globulins: transports lipids, carbohydrates, hormones, ions, antibodies, and complement
    3. Fibrinogen: blood clotting
    4. Most plasma proteins synthesized by liver
    5. Gamma globulins synthesized by plasma cells (B cells)

          

  3. White Blood Cells: Diapedesisattraction (chemical) to and movement toward foreign materials or damaged cells. Accumulation of dead white cells and bacteria is pus.

          

  4. Differential WBC count...

          

  5. LeukocytosisHigh WBC count (above 10,000)
    Note: don't need to know the numbers
