A Less Complex Representation of
the Clotting Cascade System
External: Cuts to Finger
Internal: Vessel Damage
Types of Wound and Blood Vessel Damage
The 4 Stages of Haemostasis:
1: Vascular Constriction
2: Aggregation (Platelet formation
3: Coagulation (clotting of Fibrin)
4: Dissolution: Clot removal
