Verified step by step guidance
1
Understand the hepatic portal system: It is a network of veins that carries blood from the gastrointestinal tract and spleen to the liver.
Identify the main components of the hepatic portal system: These include the portal vein, splenic vein, and superior mesenteric vein.
Recognize the function of the portal vein: It is the main vessel in the hepatic portal system, receiving blood from the splenic and superior mesenteric veins.
Consider the role of the inferior vena cava: It is a large vein that carries deoxygenated blood from the lower body to the heart, not directly involved in the hepatic portal system.
Determine which option is not part of the hepatic portal system by identifying the vessel that does not transport blood to the liver for processing.
