5 Matching questions

  1. Thrombocytopenia
  2. reason for high hematocrit
  3. White Blood Cells: Chemotaxis
  4. Formation of WBC
  5. White Blood Cell Counts
  1. a attraction (chemical) to and movement toward foreign materials or damaged cells. Accumulation of dead white cells and bacteria is pus.
  2. b too little platelets (bleeding to death)
  3. c 1. Stimulated by colony stimulating factor
    2. ones that die signal to make new ones
    3. interleukin = cause WBC formation
  4. d 1. too many RBCs
    2. dehydration
  5. e 1. Procedure used to count number of WBCs per cubic millimeter of blood
    a. 5,000 - 10,000 per cubic millimeter of blood
    2. Leukopenia
    a. Low WBC count (below 5,000)
    3. Leukocytosis
    a. High WBC count (above 10,000)
    4. Differential WBC count
    a. Lists percentages of types of leukocytes

5 Multiple choice questions

  1. 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. Type B
    Antigen B on RBC
    Anti-A antibody in serum
  3. keeps blood from clotting in area of infection
  4. 1. Erythropoiesis - formation of RBC

    2. Erythropoietin - make RBC by releasing this hormone, released by another tissue.

    stem cell: divides, one stays stem cell, one becomes WBC, RBC or platelets
  5. too many platelets (too much clotting)

5 True/False questions

  1. ABO Blood Groups: Type ABType B
    Antigen B on RBC
    Anti-A antibody in serum

          

  2. ABO Blood Groups: Type OType O
    Neither antigen A nor antigen B on RBC
    Both anti-A and anti-B antibodies in serum

          

  3. Erythropoiesis1. 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

          

  4. Hemoglobin1. Percent of blood (volume) that is RBCs - by centrifruge
    2. Indicates problem but not what problem is
    3. Normal 38-45%

          

  5. Hematocrit1. Percent of blood (volume) that is RBCs - by centrifruge
    2. Indicates problem but not what problem is
    3. Normal 38-45%
