5 Matching questions

  1. Red blood count (RBC)
  2. Erythrocytes
  3. ABO blood group
  4. Least common blood type in the US
  5. Thrombocytes
  1. a number of red blood cells per microliter of blood
  2. b Red Blood Cells. Biconcave, anucleate. Made up of Hemoglobin, lipids, ATP, and carbonic anhydrase. Transport oxygen from lungs to tissues and carbon dioxide from tissues to lungs
  3. c AB negative
  4. d Cell fragments pinched off from megakaryocytes in red bone marrow. Important in preventing blood loss by platelet plugs and promoting formation and contraction of clots
  5. e type A blood has type A antigens and Anti-B antibodies. Type B blood has type B antigens and Anti-A antibodies. Type AB has A and B antigens and no antibodies. Type O has no antigens and both A and B antibodies

5 Multiple choice questions

  1. Plasma=liquid portion, 55% of blood. Formed elements with white blood cells at the top, 45% of blood.
  2. Transport of gases by hemoglobin without oxygen.
  3. Production of red blood cells. Stem cells form proerythroblasts which become early (basophilic erythroblasts), then intermediate (polychromatics), then late erythroblasts, extrusion of nucleus becomes reticulocytes, normally 1-3%
  4. Release histamine to increase inflammatory response, and release heparin and anticoagulant, increased due to ALLERGIES or inflammation.
  5. Red blood cells (erythrocytes), White blood cells (leukocytes) can be granulocytes or agranulocytes, and Platelets (thrombocytes)

5 True/False questions

  1. Carbonic acidstoppage of bleeding caused by coagulation of blood, platelet plug formation, and vascular spasm


  2. Extrinsic pathwaybegins with chemicals that are inside the blood beginning common pathway


  3. Prothrombin time measurementhow long it takes for blood to start clotting, usually 9-12 seconds


  4. Common pathwaybegins with chemicals outside of the blood. Thromboplastin, or tissue factor (TF), is released activating factor X and beginning a common pathway.


  5. Anticoagulantsprevent clotting; antithrombin, heparin, prostacyclin, EDTA, sodium citrate
