1

Clot retraction is due to the actionnif the

PlateletsThrombinClacium

2

Vitamin k dependent factors

Factors 2,7,9,10

3

The component of the prothrombin activator complex most responsible for the generation of trombin is

Factor X

4

Responsible for the removal of unnecessary clot via fibrinolysis

Plasmin

5

The extrinsic pathway differs from the intrinsic pathway becayse

It requires the release of tissue factor thromboplastin

6

Effect of warfarin

Inhibits vitamin k dependent coagulation factors

7

Factor I (fibrinogen)II (prothrombin)VVIIX

8

Activated partial thromboplastin time assess integrity of

Intrinsic systemFactors XII, Xi, VIII, IX

9

Prolonged aPTT may be due to taking (drug)

heparin anticoagulant

10

Clot retractions is due to the action of

PlateletsCalciumThrombin

11

Vitamin K dependet factors

Factors 2, 7, 9, 10

12

Component of the prothrombin activator complex most responsible for the generation of thrombin

Factor X

13

Responsible for the removal of unnecessary clot via fibronolysis

Plasmin

14

The extrinsic pathway differs from the intrinsic pathway because

The extrinsic pathway requires the release of tissue factor thromboplastin
