The pancreas in the human body releases pancreatic juices that aid in digestion, by breaking down foods as they pass through the small intestine. The pancreas also produces hormones, like insulin, which the body needs to function. The Pancreaticoduodenal veins are veins located in the pancreas. The arteries and veins function as a transportation system in the human body. The veins carry blood to the heart, while the arteries carry blood from the heart to other parts of the body. The heat oxygenates the blood, making it healthier and the veins carry unhealthy blood from the pancreas and nearby areas. The vein is closely related to the inferior and superior pancreaticoduodenal artery. The arteries carry blood to the pancreas and duodenum, which is the first part of the small intestine. The superior artery is located both in front of and behind the pancreas. The Pancreaticoduodenal veins drain into the portal vein, which transports blood to the liver, from the intestines and stomach, before transporting it to the heart.
