The right gastric vein is a blood vessel that drains blood from the stomach. It typically runs along the lesser curvature of the stomach and collects blood from the gastric mucosa. This vein usually empties into the portal vein, which is responsible for transporting blood from the gastrointestinal tract to the liver. The right gastric vein is important for maintaining proper blood flow and nutrient absorption in the stomach. It works in conjunction with other veins, such as the left gastric vein and the gastroepiploic veins, to ensure efficient circulation within the digestive system.
