Normal hemostasis and coagulation 2. platelet: (1) adhesion to subendothelial connective tissue by Gpib、WF (2) aggregation formation of platelet thrombus by GPib/Ⅲa (3) release phosphatide-Arachidonic Acid -TXA2 further platelet activation and adhesion vIOlent vessel spasm
Normal hemostasis and coagulation 2. platelet： （1）adhesion： to subendothelial connective tissue by GPⅠb、vWF （2）aggregation ： formation of platelet thrombus by GPⅡb/Ⅲa （3）release： phosphatide-Arachidonic Acid -TXA2 further platelet activation and adhesion violent vessel spasm
Normal hemostasis and coagulation 3. coagulation: (1) Rearrangement of platelet membrane phosphatidate-PF3 (2) Tissue injury- TF release (3) Subendothelial connective tissue-Ⅻ-Ⅻa triggering intrinsic and extrinsic pathway- White thrombus-red thrombus
