Final Answer :
E
Explanation :
The hepatic portal system is responsible for directing blood from parts of the gastrointestinal tract to the liver. The gastric vein and the inferior mesenteric vein are both components of this system, carrying blood from the stomach and the lower part of the large intestine, respectively, to the liver for detoxification and nutrient processing. The azygos vein and the inferior vena cava are not part of the hepatic portal system; they are components of the systemic venous system.
