1

The PT and the PTT pathway meet at factor:

X, because “X” marks the spot

2

Factor______is a cofactor for factor X, and you can remember this because ______fits into the notch of the X

V

3

Factor Xa converts prothrombin (Factor II) into ______, the most important enzyme on the planet

thrombin

4

Thrombin, among other things, converts the soluble molecule fibrinogen into a:

solid fibrin clot

5

The Common Pathway money memory device

$ Small Bills: 10, 5, 2, 1
V + X
II = prothrombin
I = fibrinogen



6

You can remember the factors in the common pathway by remembering the bills in your wallet smaller than a ______. Don’t forget the $2 bill !!

$20

7

Factor Xa converts ______ (Factor II) into thrombin, the most important enzyme on the planet

prothrombin

8

PT has one less letter than PTT, and PT values are shorter than PTT values, because the pathway is______

Xa

11

_______ converts the soluble molecule fibrinogen into a solid fibrin clot

12

Deficiency of___________will prolong the PT but not the PTT

Factor VII

13

Deficiencies of Factors ____________ will prolong the PTT and not the PT.

Remember that factor 10 is in the common pathway, and affects BOTH the PT and the PTT

12, 11, 9 and 8
