The right gastroepiploic vein plays a significant role in the vascular system of the digestive tract by collecting blood from the greater curvature of the stomach and the adjacent regions of the intestine. This vein specifically drains into the superior mesenteric vein, which is responsible for collecting blood from the small intestine and parts of the large intestine.

The superior mesenteric vein is crucial as it merges with the splenic vein to form the hepatic portal vein. This pathway directs blood to the liver for processing before it reaches the systemic circulation. Understanding the specific drainage patterns of venous structures in the gastrointestinal system is essential for comprehending the relationships between various organs and their vascular supply.
