Question

Quizplus · Accepted Answer

The portal vein brings blood from the gastrointestinal tract, pancreas, and spleen to the liver for processing. This blood is rich in nutrients and other molecules that the liver can metabolize, but it is not yet oxygenated. The hepatic artery, which branches from the celiac trunk, supplies oxygenated blood to the liver. The jugular vein drains blood from the head and neck, and does not directly connect to the liver. The hepatic veins drain blood from the liver back into the systemic circulation.
