Samplex 2nd LE Flashcards
Clot retraction is due to the actionnif the
PlateletsThrombinClacium
Vitamin k dependent factors
Factors 2,7,9,10
The component of the prothrombin activator complex most responsible for the generation of trombin is
Factor X
Responsible for the removal of unnecessary clot via fibrinolysis
Plasmin
The extrinsic pathway differs from the intrinsic pathway becayse
It requires the release of tissue factor thromboplastin
Effect of warfarin
Inhibits vitamin k dependent coagulation factors
Prolonged prothrombin time assesses deficiency in what factors of coagulation?
Factor I (fibrinogen)II (prothrombin)VVIIX
Activated partial thromboplastin time assess integrity of
Intrinsic systemFactors XII, Xi, VIII, IX
Prolonged aPTT may be due to taking (drug)
heparin anticoagulant
Clot retractions is due to the action of
PlateletsCalciumThrombin
Vitamin K dependet factors
Factors 2, 7, 9, 10
Component of the prothrombin activator complex most responsible for the generation of thrombin
Factor X
Responsible for the removal of unnecessary clot via fibronolysis
Plasmin
The extrinsic pathway differs from the intrinsic pathway because
The extrinsic pathway requires the release of tissue factor thromboplastin
What factors are missing in hemophilia
I dont know
State the effect of warfarin (coumadin)
Inihibits vitamin k-dependent coagulation factors
Responsible for the biconcave shape and structural integrity of RBC membrane
Spectrin
Globin chains of adult RBC
2 alpha, 2 beta
Binding of epo to the cytkine receptor leads to the
Transcription of GATA-1
Pernicious anemia is due to
failure to produce intrinsic factor, poor absorption of vitamin b 12
