| A | B |
|---|
| blood ph | 7.35-7.45 |
| proteins in plasma | albumin, globulins, & bld clotting factors |
| plasma | liquid part of blood |
| albumin | made by liver, keeps blood thick |
| globulins | made by liver, antibodies |
| hematocrit | formed elements of blood |
| erythropoietin | hormone produced by kidneys, stims RBM |
| hemopoietic tissue | produces RBCs |
| 120 days | lifespan of RBCs |
| normal level of erythrocytes | 4.5-5.5 |
| normal level of hematocrit | 45% |
| normal level of hemoglobin | 12-18 |
| days, months, years | lifespan of WBCs |
| normal value | 5,000-10,000 |
| neutrophils | most abundant WBC |
| lymphocytes | WBC, produce antibodies |
| eosinophils | increase w/ allergic reaction |
| basophils | increase w/ inflammatory reactions |
| histamine | released when tissues are injured |
| 1st neutrophils 2nd monocytes | attracted to area when injured |
| thrombocytes | also called platelets |
| platelets | purpose is blood clotting |
| structure of thrombocytes | fragments of a megakaryocyte |
| lifespan of platelet | about 10 days |
| normal lab value | 150,000-300,000 |
| blood clotting factors | platelets, thrombin, fibrinogen |
| platelets release this when activated | serotonin |
| purpose of serotonin | constrict blood vessels |
| thromboplastin | initiates bld clotting cascade |
| prothrombin changes to this | thrombin |
| causes fibrinogen to change to fibrin | thrombin |
| normal clottting time | 2-6 mins |
| universal donor | O- |
| universal recipient | AB+ |
| antigen | activates immune system, some are self |
| agglutination | clumping |
