5 Matching questions

  1. Differential white blood cell count
  2. Complete blood count (CBC)
  3. Intrinsic pathway
  4. Monoblasts
  5. Neutrophils
  1. a percentage of each of the five kinds of white blood cells in the WBC.
  2. b Develop into monocytes
  3. c Small phagocytic cells, most common
  4. d red blood count, hemoglobin and hematocrit measurements, white blood count, and differential white blood coint
  5. e begins with chemicals that are inside the blood beginning common pathway

5 Multiple choice questions

  1. accumulation of platelets that can seal up small breaks in blood vessels. Platelet adhesion occurs when platelets bind to collagen exposed by blood vessel damage, activating them (adhesion mediated through von Willebrand factor), platelet release reaction-cascade of chemicals are released by platelets activating more platelets, change shape and express fibrinogen receptors and platelet aggregation occurs
  2. 250,000-400,000 platelets per microliter of blood. Thombocytopenia is a condition where platelet count is greatly reduced resulting in chronic bleeding
  3. Red blood cells (erythrocytes), White blood cells (leukocytes) can be granulocytes or agranulocytes, and Platelets (thrombocytes)
  4. percentage of total blood volume composed of red blood cells. Normocytes are normal sized, microcytes are smaller than normal, macrocytes are larger than normal
  5. Develop into red blood cells

5 True/False questions

  1. MonocytesBecome macrophages


  2. LymphocytesImmunity, increase due to viral infection, smallest, stimulate production of antibodies


  3. Most common blood type in the USextrinsic and intrinsic pathways converge. Prothrombinase-> prothrombi-> thrombin which converts fibrinogen to insoluble protein fibrin forming a fibrous network of the clot


  4. Hematopoiesis or hemopoiesisProcess of blood cell production


  5. Plateletsthrombocytes, minute fragments of cells consisting of a small amount of cytoplasm surrounded by plasma membrane. Derived from megakaryocytes. Form platelet plugs, promote formation and contraction of clots. Have proteins and glycoproteins allowing them to attach to other molecules. Contain actin and myosin
