- Thrombosis (The blood clotting process)
- Step 1 - Platelet touches damaged vessel wall - change from flattened discs to spheres
- Step 2 - Platelets stick to the exposed collagen and other platelets forming a temporary platelet plug
- Step 3 - Platelets release substances to attract other platelets
- Step 4 - Thromboplastin is released from platelets and damaged tissue
- Step 5 - Calcium and Vitamin K in the plasma act with thromboplastin to catalyse the conversion of prothrombin to thrombin
- Step 6 - Thrombin catalyses the conversion of fibrinogen to fibrin
- Step 7 - Fibrin strands form a net to trap the red blood cells and form a clot
