• False

The final step in coagulation is the formation of ________.

•  

  prothrombin activator

  
  

• fibrinogen

• fibrin

• thrombin

These are the most abundant leukocytes, constituting 40-70% of all white blood cells.

Which body activity would be most affected if a patient lacked an adequate number of erythrocytes (anemia)?

• clotting

•  

  oxygen transport

  
  

•  

  immune response

  
  

•  

  hormone transport

  
  

Which of the following might trigger erythropoiesis?

•  

  moving to a lower altitude

  
  

•  

  hypoxia of EPO-producing cells

  
  

•  

  decreased tissue demand for oxygen

  
  

•  

  an increased number of RBCs

• False

The biconcave shape of an erythrocyte is advantageous because it:

• Makes it easier for the cell to be phagocytized

  
  

• Stores more hemoglobin

  
  

• Increases its surface area for gas exchange

  
  

• Helps in blood clotting
