A Complex Concept: The Clotting Cascade Process

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
