The gastroduodenal artery is indeed located in the anterolateral part of the pancreatic head. This artery branches off from the common hepatic artery and plays a significant role in supplying blood to the stomach and the duodenum, as well as providing branches that contribute to the blood supply of the pancreas. Its proximity to the pancreatic head is crucial because the area requires adequate blood flow for the functioning of both the pancreas and neighboring structures.

Understanding the anatomy of the pancreatic head is important not just in terms of blood supply, but also in relation to surrounding organs and their blood vessels. The superior mesenteric artery, for instance, is located posterior to the neck of the pancreas, not in the anterolateral region. The pancreatic duct runs through the pancreas but is not located in the anterolateral part of the head. The inferior mesenteric artery, on the other hand, supplies the distal colon and is situated far from the pancreatic head. This context reinforces the understanding of vascular relationships within the upper abdomen, particularly concerning the pancreas.
