Coagulation

Factors II, V, VIII, HMWK -> cofactors

Factors II, VII, 9-12, Prekallikrein -> serine proteases

Vitamin K Dependent Factors

• Serine Proteases
  • Factors II, VII, IX, X
  • Regulatory control proteins C, S, Z

Factor	Other Names	Pathway(s)	Role	Location of Synthesis
I	Fibrinogen
II	Prothrombin
III	Tissue Factor (TF)
IV	Ca2+
V	Labile factor
VII	Stable factor
VIII	Anti-hemophilic factor
IX	Christmas Factor
X	Stuart-Prower Factor
XI	PTA (Plasma Thromboplastin Antecedent)
XII	Hageman Factor
XIII	Fibrin Stabilizing Factor (FSF)			Crosslinks adjacent fibrin strand D-domains to make an insoluble polymer
VWF
HMWK

Protein Z

• Z-dependent protease inhibitor (ZPI)
• Protein Z enhances ZPI activity
  • inhibits factor X and XI

Restoring Blood Flow

• Fibrinolytic proteins
  • Plasminogen
    • Converted into plasmin by TPA and UPA
    • Plasmin helps restore blood flow
  • TPA
  • UPA
