What activates extrinsic pathway?
ExtrinsicClotting Cascade.Activatedfactor Xa is the site at which the intrinsic andextrinsiccoagulation cascades converge. Theextrinsic pathwayis initiated at the site of injury in response to the release of tissue factor (factor III) and thus, is also known as the tissue factorpathway.Oct 2, 2017

What is intrinsic and extrinsic pathway of blood clotting?
Theclottingcascade occurs through two separate pathways that interact, theintrinsicand theextrinsic pathway. Theextrinsic pathwayis activated by external trauma that causesbloodto escape from the vascular system. Thispathwayis quicker than theintrinsic pathway. It involves factor VII.
