WebThe coagulation cascade refers to the series of steps that occur during the formation of a blood clot after injury by activating a cascade of proteins called clotting factors. There are three pathways: intrinsic, extrinsic, and common. The intrinsic pathway is activated by factors in the blood, while extrinsic is activated by tissue factor. WebThe intrinsic pathway is initiated by the activation of factor XII by certain negatively charged surfaces, including glass. High-molecular-weight kininogen and prekallikrein are two proteins that facilitate this activation. The enzyme form of factor XII (factor XIIa) catalyzes the conversion of factor XI to its enzyme form (factor XIa).
