- 1.Platelets
- 2.Sticky platelets
- 3.Thromboplastin into thrombin
- 4.Fibrinogen into fibrin
- 5.Fibrin mesh
- Blood clot
- Traps more platelets and red blood cells, forming the clot
- Fibrinogen (soluble protein) converts into fibrin (long, insoluble strands) via thrombin
- 5.Fibrin mesh
- Thromboplastin (protein) released from damaged tissue and activated platelets
- Thromboplastin activates clotting cascade
- Thromboplastin + Ca2+ and Vitamin K activate enzyme which converts prothrombin into thrombin (an enzyme)
- 4.Fibrinogen into fibrin
- Stick to each each other and exposed collagen to form platelet plug
- 3.Thromboplastin into thrombin
- In contact with a damaged blood vessel wall
- 2.Sticky platelets
