| whole blood is made of what two key components | blood plasma and formed elements |
| blood plasma is made of what 2 key components? | proteins, water, and other solutes |
| what are 3 main proteins found in the blood | albumins, globulins, fibrinogen |
| what are the 6 solutes commonly found in the blood | electrolytes, nutrients,gases, regulatory substances, vitamins, waste products |
| what is a formed element | cells and cell fragments |
| what are the three classes of formed elements | red blood cells, white clood cells, platelets |
| what are the 5 classes of white blood cells | neutrophils, lymphocytes, monocytes, eosinophils, and basophils |
| whats the relationship between the terms erythrocyte and erthropoesis | erythrocyte ejects its nucleus & erthropoesis is the formation of red blood cells |
| whats the relationship between reticulocytes and red blood cells | reticulocytes are premature red blood cells |
| whats the role of a neutrophil | they aid in the removal of noxious stimuli that cause cell death |
| whats the role of a monocyte | they replenish macrophages and dendrites to a normal state |
| whats the role of an eosinophil | they destroy foreign cells and destroy parasites |
| whats the role of basophil | they kill bacteria and parasites but can react bad and cause asthma |
| whats the role of B T and natural killer cells? | the natural killer cells defend from tumors and T and B eliminate pathogenic cells |
| whats hemostasis | a sequence of responses that stops bleeding when blood vessels are injured |
| what are the 3 methods of reduction of blood loss | vascular spasm, blood clotting, platelet plug formation |
| how does a vascular spasm aid in hemostasis | the smooth muscle contracts and it reduces blood loss for several hours the refexes are initiated by its receptors as platelts accumulate at the damaged site they release chemicalsthat enhance vasoconstriction |
| how does a platelet plug aid in hemostasis | they help fill in the gap in the injured blood vessel wall |
| how does clotting aid in hemostasis? | various chemicals known as clotting factos and molecules associated with platlets or damaged tissues activate each other |
| whats the difference between a thrombus and embolus | thrombus may dissolve instantly and embolus is a blood clot, a bubble of air |
| whats a pulmonary embolism and why is one dangerous | an embolus in the lung would result in a hear attack or kidney failure |
| what makes one blood type different from another | the amount of antigens on the RBC's |
| how is type A different from type B | A has A antigen and B has B antigen |
| how is type AB different from type A or B | group AB has A and B antigen and A and B only have one |
| what does an a antibody do and what dos a b antibody do | A antibody reacts with antigen A B antibody reacts with antigen B |
| who has an a antibody who does not | type B has antibody A type O has antibody a and b |
| who has a b antibody who does not | Type O has antibody a and B |
| what happens in an incompatible blood transfusion? | the donor cells are treated as if they were foreign invaders and the immune system will attack them but potentially fail and cause death or other complications |
| whats the difference between Rh+ and Rh- blood? | positive has the antigen negative does not and negative cant be given to or identified |
| what is anemia and what are the symptoms? | its a condition in which the oxygen carrying capacity of blood is reduced and they have hemoglobin, fatigue, and theyre cold and pale |
| whats the cause of iron deficiency anemia? | menstrual blood loss |
| whats the cause of pernicious anemia | insufficient hemosposis |
| whats the cause of hemorrhagic anemia? | excessive loss of RBC's through bleeding with large woulds or ulcers |
| whats the cause of hemolytic anemia? | outside agents like parasites toxins antibodies |
| whats the cause of thalassmeia anemia | hereditary |
| whats the cause of aplastic anemia | destruction of red bone marrow by radiation meds or toxins |
| whare are the causes and symptoms of sickle cell anemia | their rbs's have abnormal hemoglobin and rupture easily with extensive tissue damage |
| what are the causes and symptoms of hemophilia | inherited deficiency of clotting where bleeding may occur after minor trauma like random nose bleeds |
| what are the causes and symptoms of leukemia | uncontrolled production and accumulation of immature leukocytes which wont die |
| whats a reticylocyte | counting the colume of reticulocytes in a sample of blood. measures the rate of erythropoesis |
| whats a hematocrit | counting the % of a blood sample that is composed of rbcs diagnosis anemia |
| differential wbc count | count various forms of wcs to assess for infections an manufacture of wbcs |
| complete blood count | measures volume of all blood components, measures blood components that are out of range |
| emia | blood condition |
| erythro | red |
| gluco | sugar, glucose |
| glyco | sugar, sweet |
| hemo hemato | blood, hemmorrhage |
| rrhagia | hemorrhage excessive discharge |
| phlebo | vein |
| thrombo | blood clot |
