Does the bile duct join small intestine at duodenum?

Yes, the bile duct joins the small intestine at the duodenum.

The duodenum is the first part of the small intestine, and it is where the bile duct and the pancreatic duct empty into the digestive tract. The bile duct carries bile from the liver and gallbladder, which helps to digest fats. The pancreatic duct carries enzymes from the pancreas that help to digest carbohydrates, proteins, and fats.
