Intrinsic Pathway: The intrinsic pathway of blood coagulation is one of the two main pathways that lead to the formation of a fibrin clot. It is initiated by the activation of factor XII and involves the sequential activation of several other clotting factors, including factor IX.
Hemostasis: Hemostasis is the physiological process that stops bleeding by forming a blood clot. It involves the coordination of platelet activation, blood vessel constriction, and the coagulation cascade, with factor IX being a key player in the intrinsic pathway of coagulation.
Fibrin Clot: A fibrin clot is the final product of the blood coagulation process, formed by the cross-linking of fibrin monomers. Factor IX contributes to the stability and strength of the fibrin clot, helping to prevent excessive bleeding and promote wound healing.
