5 Written questions

5 Matching questions

  1. Platelets - function
  2. Agglutination
  3. Hemoglobin
  4. Thrombocytopenia
  5. ABO Blood Groups: Type O
  1. a 1. Functions
    a. Transport of chemicals important to the clotting process.
    b. Formation of a temporary patch in the walls of damaged blood vessels.
    c. Active contraction after clot formation has occurred.
  2. b Type O
    Neither antigen A nor antigen B on RBC
    Both anti-A and anti-B antibodies in serum
  3. c 1. Normals
    a. Male 14-16 g/dl
    b. Female 12-14 g/dl
    2. carries oxygen
    3. pigment of blood - hemoglobin mixing w/oxygen
    4. contain iron, needed to make hemoglobin
  4. d clumping of red blood cells in response to a reaction between an antibody and an antigen
  5. e too little platelets (bleeding to death)

5 Multiple choice questions

  1. glucose, amino acids, triglycerides, cholesterol, vitamins
  2. Liquid 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
  3. 1. Protein that reacts against a specific antigen
    2. in the plasma
    3. goes after foreign blood types. For example, if you are type A & you get type B, antibody will go after type B
    Note: antibodies is what on test, not agglutinins
  4. 1. Stimulated by colony stimulating factor
    2. ones that die signal to make new ones
    3. interleukin = cause WBC formation
  5. 1. Rh-positive
    a. Rh antigen on RBC
    b. No antibody in serum
    2. Rh-negative
    a. No Rh antigen on RBC
    b. No antibody in serum
    3. Anti-Rh antibodies are not normally present in blood

5 True/False questions

  1. RBC formationclumping of red blood cells in response to a reaction between an antibody and an antigen

          

  2. heparin1. 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

          

  3. Plateletsthree 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)

          

  4. 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

          

  5. 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.
