Aorta

Inferior vena cava

Hepatic portal vein

Superior mesenteric artery

Verified step by step guidance

Identify the function of each blood vessel mentioned in the options. The aorta is the main artery that carries oxygenated blood from the heart to the rest of the body. The inferior vena cava carries deoxygenated blood from the lower body to the heart. The superior mesenteric artery supplies blood to the small intestine.

Understand the role of the hepatic portal vein. It is a vessel that carries nutrient-rich blood from the gastrointestinal tract, specifically the small intestine, to the liver for processing.

Recognize that the liver is a key organ for processing nutrients absorbed from the digestive tract. It detoxifies chemicals, metabolizes drugs, and processes nutrients absorbed from the small intestine.

Determine which blood vessel directly connects the small intestine to the liver. The hepatic portal vein is responsible for transporting nutrients directly from the small intestine to the liver.

Conclude that the hepatic portal vein is the correct answer, as it is the large blood vessel that transports nutrients from the small intestine directly to the liver for processing.
