Clotting Overview
- Endothelial Cells are Damaged
- Platelets Respond to Exposed Collagen and Stick
- Platelets Release Recruiting Factors
- More Platelets are Attracted
- Soluble Fibrinogen Turns to Insoluble Fibrin
- Fibrin Seals the Clot
- Clot Dissolves
- Liver Produces Clotting Factors
Coagulation Cascade
- Secondary Hemostasis
- Intrinsic Pathway
- Partial Thromboplastin Time (PTT)
- Heparin
- Extrinsic Pathway
- Prothrombin Time (PT)
- Warfarin
- Common Pathway
