WebApr 23, 2016 · Alternatively, coagulation may be initiated through the “intrinsic pathway” when factor XII is activated on a charged surface by a process called contact activation. 20–22 Activation of factor XII is followed sequentially by activation of factor XI and factor IX. WebFeb 18, 2024 · Next, a platelet plug forms to temporarily seal small openings in the vessel. Coagulation then enables the repair of the vessel wall once the leakage of blood has stopped. (b) The synthesis of fibrin in blood clots involves either an intrinsic pathway or an extrinsic pathway, both of which lead to a common pathway. (credit a: Kevin MacKenzie) taxi elda novelda
