Extrinsic Pathway

The extrinsic pathway is one of the ways our body initiates blood clotting, which is essential for healing injuries. It starts when tissue damage exposes certain proteins that attract clotting factors from the blood. These proteins form a complex that activates a key clotting factor called Factor X. This, in turn, leads to the formation of a fibrin mesh that stops bleeding by sealing the wound. The extrinsic pathway works quickly, making it crucial in responding to external injuries, while another pathway, the intrinsic pathway, operates more slowly from within the bloodstream. Together, they ensure effective clotting.
