The ________ Carries Nutrient-Rich Blood into the Liver

Question

The ________ carries nutrient-rich blood into the liver.
A) hepatic artery
B) gastric vein
C) myenteric capillaries
D) hepatic portal vein
E) superior mesenteric vein

Accepted Answer

The hepatic portal vein carries nutrient-rich blood from capillaries in the stomach, intestines, pancreas, and spleen into the liver for processing and detoxification. The hepatic artery carries oxygenated blood to the liver but does not specifically carry nutrient-rich blood. The gastric vein drains blood from the stomach, not necessarily nutrient-rich blood. The myenteric capillaries are not a specific blood vessel, but rather refer to the network of capillaries in the smooth muscle layer of the gastrointestinal tract. The superior mesenteric vein drains blood from the small intestine, ascending colon, and transverse colon, but again, it is not specifically described as carrying nutrient-rich blood.
