THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The accessory pancreatic duct (APD) is the main drainage duct of the dorsal pancreatic bud in the embryo, entering the duodenum at the minor duodenal papilla (MIP). With the growth, the duct of the dorsal bud undergoes varying degrees of atrophy at the duodenal end.

Detailed explanation-2: -The ventral duct forms the proximal portion of the major pancreatic duct, which opens into the duodenum via the ampulla of Vater. The dorsal duct forms a part of the major ducts as well as the minor duct or the accessory duct of Santorini.

Detailed explanation-3: -The pancreas is solid (acinar tissues), and contains drainage tubes (the pancreatic ductal system). The pancreatic juices are made in the acinar tissues, and passed by secretion into the tubes (ducts) for transport into the duodenum. The exit hole into the duodenum is called the papilla of Vater.
