Study Notes
Coagulation Factors
- Thrombin plays a crucial role in coagulation by converting fibrinogen into fibrin, leading to clot formation.
- Factor Xa is responsible for converting prothrombin to thrombin.
Anticoagulants
- Anticoagulant drugs, such as warfarin, inhibit the action of coagulation factors to prevent clot formation.
- Unfractionated heparin and Low Molecular Weight Heparins (LMWHs) are types of anticoagulants that inhibit thrombin and factor Xa.
Tissue Factors
- Tissue factors play a key role in coagulation by initiating the clotting cascade.
- Tissue factors activate factor VII, which then activates other coagulation factors.
Vasospasm
- Vasospasm helps to reduce blood flow to the affected area, allowing the clotting process to occur.
- The primary function of vasospasm is to constrict blood vessels and facilitate coagulation.
Fibrin Generation
- Thrombin is ultimately responsible for generating fibrin in coagulation.
- Fibrin is essential for clot formation and wound healing.
