On the exogenous path, activation takes place very quickly (within seconds), while on the endogenous path, activation takes place over a larger number of intermediate stages and takes longer (minutes). As a rule, both systems are involved in the normal coagulation process. The common final stage of the two activating systems finally makes prothrombin (factor II) and vitamin K formed in the liver is converted into thrombin. The thrombin thus formed is an enzyme, which also synthesizes the fibrinogen (factor I) and thus initiates the formation of fibrin.
