The process of clot formation

1. injury occurs (blood vessel damaged) 2. hemorrhage begins 3. platelets activated, clump at site of damage 4. thromboplastin, released from platelets, reacts with calcium ions 5. prothrombin is converted to thrombin 6. fibrinogen forms fibrin 8. fibrin traps RBC’s and platelets, forming a blood clot 9. blood clot seals the damaged vessel
