1. Damage to a blood vessel
2. Platelets activated and release clotting factors inc. thromboplastin (platelets can form a plug to seal minor damage)
3. Platlets catalyse the conversion of prothrombin to thrombin with the addition of calcium ions, vitamin K and clotting factors
4. Thrombin catalyses the conversion of fibrinogen to fibrin
5. Fibrin forms a mesh that traps RBCs to form a clot
