| A | B |
|---|
| ABO | most commonly used blood groups and typing |
| Albumin | blood protein that maintains osmotic pressure |
| Anemia | condition with not enough RBCs and/or hemoglobin |
| Antibodies | proteins found in plasma that react with antigens; agglutinins |
| Anticoagulant | substance that inhibits clotting |
| Antigens | protein markers found on RBCs; agglutinogens |
| Anucleate | no nucleus |
| Blood | fluid connective tissue |
| Blood doping | drugs or transfusions which enhance the number of RBCs |
| Chemotaxis | chemical attraction of WBCs to disease or injury site |
| Clotting | coagulation; process that produces clot; involves clotting factors |
| Cross match | mixing of donor and recipient blood to test compatibility |
| Embolus | moving clot |
| Emigration | WBCs leaving the blood stream |
| Eosinophil | WBC with red staining granules; can emigrate; becomes wandering macrophage |
| Erythrocyte | red blood cell |
| Erythropoiesis | formation of red blood cells |
| Erythropoietin | produced by the kidney; increases the number of RBC precursors |
| Extrinsic | clotting pathway that occurs rapidly; clotting factor leaks into blood from cells outside vessels |
| Fibrinogen | blood protein for clotting |
| Fibrinolytic | system that dissolves small |
| Globulins | blood proteins that are part of the immune system |
| Hematocrit | blood test giving RBCs as a percentage of cells found in whole blood |
| Hematology | science that studies blood |
| Hematopoiesis | process of blood formation |
| Hemoglobin | red protein in RBC that carries oxygen |
| Hemorrhage | loss of large amounts of blood from vessels |
| Hemostasis | blood clotting process |
| Hypoxia | body cells not getting enough oxygen |
| Interstitial | fluid which bathes tissues |
| intrinsic | clotting pathway that is more complex and occurs more slowly; activators are in the blood |
| leukemia | malignant cancer of the blood and bone marrow |
| leukocyte | white blood cell |
| leukocytosis | high WBC count due to microbes |
| leucopenia | low WBC count due to radiation |
| lymphoid | stem cells that give rise to lymphocytes |
| MHC | antigens on WBCs that are unique for each individual (initials) |
| myeloid | stem cells that give rise to RBCs |
| Sickle cell | type of anemia in which a single amino acid error in the hemoglobin molecule causes the RBC to sickle |
| Thalassemia | inherited disorder that produces abnormal alph or beta hemoglobin chains |
| Thrombocyte | platelet |
| Thrombopoietin | hormone produced by the liver; stimulates formation of platelets |
| Thrombosis | clot formed in a an unbroken vessel |
| Transfusion | transfer of whole blood or blood components |
| Typing | determination of a blood type |
| Vascular spasm | smooth muscle contraction in small blood vessels; reduces blood loss for up to several hours |
