The inferior mesenteric vein drains the blood from the lower portion of the large intestine and joins with the splenic vein to form the portal vein, which carries blood to the liver for processing. The celiac trunk supplies blood to the upper portion of the gastrointestinal tract, while the gastric vein drains the stomach. The superior mesenteric vein drains the small intestine and part of the large intestine. The inferior vena cava collects blood from the lower part of the body and returns it to the heart.
