- Red blood count (RBC)
- ABO blood group
- Least common blood type in the US
- a number of red blood cells per microliter of blood
- 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
- c AB negative
- 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
- 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
- Plasma=liquid portion, 55% of blood. Formed elements with white blood cells at the top, 45% of blood.
- Transport of gases by hemoglobin without oxygen.
- 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%
- Release histamine to increase inflammatory response, and release heparin and anticoagulant, increased due to ALLERGIES or inflammation.
- Red blood cells (erythrocytes), White blood cells (leukocytes) can be granulocytes or agranulocytes, and Platelets (thrombocytes)
5 True/False questions
Carbonic acid → stoppage of bleeding caused by coagulation of blood, platelet plug formation, and vascular spasm
Extrinsic pathway → begins with chemicals that are inside the blood beginning common pathway
Prothrombin time measurement → how long it takes for blood to start clotting, usually 9-12 seconds
Common pathway → begins with chemicals outside of the blood. Thromboplastin, or tissue factor (TF), is released activating factor X and beginning a common pathway.
Anticoagulants → prevent clotting; antithrombin, heparin, prostacyclin, EDTA, sodium citrate
