Clotting Factor XIII

A

Fibrin-stabilizing factor

17
Q

Extrinsic pathway takes place via…

A

Damage to cells within and outside the blood vessels

18
Q

What is the extrinsic pathway portion of the coagulation cascade?

A

Tissue factor -> Proconvertin (CF7) -> Stuart-Prower Factor (CF10)

19
Q

Intrinsic pathway takes place via…

A

Exposure of collagen fibers of us endothelial cells of blood vessels to blood flow. Thus, activating clotting factors.

20
Q

Hemostasis

A

the process of stopping blood loss

20
Q

What is the intrinsic pathway portion of the coagulation cascade?

A

Collagen fibers exposed -> Hageman factor (CF12) -> Plasma Thromboplastin Antecedent (CF11) -> Christmas factor (CF9) -> Stuart-Prower Factor (CF10)
