Correct answer: BSynthesis of clotting factors

The liver synthesises most clotting factors (I II V VII VIII IX X XI XII XIII) and fibrinogen. This is a synthetic function distinct from its drug metabolism role (Phase I oxidation/reduction/hydrolysis and Phase II conjugation). Liver failure causes coagulopathy due to reduced clotting factor synthesis measured by prolonged PT/INR.
