|---|
| plasma | liquid portion of blood |
| functions of blood | transport, homeostasis |
| hematology | study of blood |
| average volume of blood | 5 liters |
| components of blood | cellular(formed elements), plasma |
| formed elements | 45% |
| plasma | 55% |
| plasma | contains H20, hormones,wastes,proteins,etc |
| formed elements | contains RBC, WBC, platelets |
| RBC | erythrocytes |
| erythrocytes RBC | contain hemoglobin |
| RBC | lack nuclei |
| RBC | average life span 120 days |
| erythropoiesis | RBC production |
| RBC production( adults) | red bone marrow |
| RBC production(fetuses | yolk sac, liver, spleen |
| erythropoietin | hormone that stimulates RBC production |
| WBC | leukocytes |
| granulocytes | neutophils, eosinophils, basophils |
| agranulocytes | monocytes, lymphocytes |
| neutrophils | most common, 50-70%, phagocytosis, fight infection |
| eosinophils | 1-4%, allergic reactions |
| basophils | less 1%,release heparin(inhibit clotting), histamine (itis) |
| monocytes | 3-8%, largest, phagocytosis |
| lymphocytes | 20-30%, large nucleus, antibodies, immunity |
| WBC | average 5000-10,000 |
| leukemia | abnormal production of leukocytes, elevated |
| platelets | thrombocytes |
| platelets | fragments of cells |
| platelets | blood clotting |
| hemocytoblast | all blood cells formed from this, cell producer |
| anemia | low Hct or Hb, cause decrease in O2 to tissues |
| sickle-cell | abnormal shaped RBC |
| polycythemia | elevated Hct with normal blood volume |
| Hemophilia | inadequate production of clotting factors |
| Trypanosoma gambiense | African sleeping sickness |
| Plasmodium | cause Malaria |
| RBC | 4-6 million/ml, 25 trillion in adult |
| platelet | 130,000-360,000 |
| RBC | no nucleus |
| hematocrit | obtains number of RBC and WBC in sample of blood |
| lymphocytes | immunity Tcells, antibodies Bcells |
| plasma proteins | albumin (osmotic press.), fibrinogen(clotting), globulins(immunity) |
| RH postive | you have antigen for it |
| RH negative | you don't have antigen for it |
| erythroblastosis fetalis | + baby and - mother |
| hemostasis | stoppage of bleeding |
| thromboplastin | aids in clotting |
| clotting sequence | prothrombin ,thrombin,fibrinogen,fibrin |
| anticlotting factors | heparin=blocks thrombin production |
| anticlotting | warfrin=vitamin k inhibitor |
| anticlotting | plasminogen=lyses clot |
| anticlotting | prostocyclin=blocks thromboxane(platelet formation) |
| thrombosis | fixed clot |
| embolism | freely drifting clot, to brain,heart,lungs |
| arteriosclerosis | fatty accumulations in arteries |
| plaminogen | breaks up blood clots |
| streptokinase | clot buster drug |
| antigens | on surface of RBC |
| antibodies | protein in plasma |
| agglutination | clumping of RBC when testing compatibility |
