Thrombosis (from Ancient Greek thrmbsis "clotting") is the formation of a blood clot inside a blood vessel, obstructing the flow of blood through the circulatory system.When a blood vessel (a vein or an artery) is injured, the body uses platelets (thrombocytes) and fibrin to form a blood clot to prevent blood loss.

Other symptoms may include movement problems, changes in mood, or changes in personality. While there may be some variations between individuals, the hepatic portal vein is usually formed by the Home Page: American Journal of Cardiology The hepatic artery delivers highly-oxygenated blood to the liver.
