THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The head of the pancreas is the enlarged part of the gland that is surrounded by the C-shaped curve of the duodenum. On its way to into the descending part of the duodenum, the bile duct lies in a groove on the posterosuperior surface of the head or is embedded in its substance.

Detailed explanation-2: -The common bile duct passes behind the pancreas and joins the pancreatic duct. The combined ducts open into the small bowel, where bile is released. The release of bile is controlled by a valve. When we eat, the gallbladder releases bile into the small bowel to help digest food.

Detailed explanation-3: -The common bile duct and the common hepatic duct together constitute the main bile duct. The lower end of the bile duct sweeps around behind the duodenum and through the head of the pancreas before joining the pancreatic duct at the main papilla (of Vater).
