<prompt> Primary abnormality in sequence of events leading to DIC is-Fibrin deposits in multiple sitesUncontrolled thrombin generationAbnormal adhesion and consumption ofplateletsDestruction of red cells  <response>: The sequence of events in DIC are: activation of coagulation, thrombotic phase,consumption phase,secondary fibrinolysis. Massive tissue injury ,infections ,widespread endothelial damage stimulates widespread activation of coagulation pathway bye release of tissue factor uncontrolled thrombin generation is the primary pathway.Reference:Harsh mohan textbook of pathology sixth edition pg no 337
