Final answer:
Warfarin prevents blood clot formation by inhibiting the synthesis of vitamin K-dependent clotting factors that are necessary for the activation of the clotting process.
Step-by-step explanation:
Warfarin prevents the formation of blood clots by interfering with the synthesis of vitamin K-dependent clotting factors in the liver. Vitamin K is necessary for the activation of clotting factors that help blood to clot. By inhibiting this process, warfarin reduces the ability of the blood to form clots.
For example, one of the clotting factors that requires vitamin K is prothrombin. Warfarin inhibits the activation of prothrombin, leading to a decrease in the production of the fibrin clot, which is essential for blood clot formation.
