Situated in the abdomen, Pancreas are pivotal in food conversion serving as fuel to the cells of the body. Mainly it has two important functions – endocrine function which checks the blood sugar level and the exocrine function which assists in digestion. It is engirdled by some vital organs of the body, such as the spleen, small intestine and liver.
The chief duct of the pancreas links with the common bile duct that supplies the bile from the gallbladder. Together, they associate with the duodenum at a point known as the Vater or the ampulla. At the point, the enzymes of the pancreas and the bile are introduced into the duodenum to assist the digestion process of proteins, fats and carbohydrates.
The spherical structure, the ampulla of Vater or the hepatopancreatic duct are situated at the region of the confluence of the pancreatic duct and the common bile duct, thus tagging the point of entrance of the bile into the duodenum (it’s second part to be precise).

(a) stomach
(b) ampulla
(c) duct of oddi
(d) duct of wirsung
Answer: (b)
Explanation: Also referred to as the Ampulla of Vater, the Hepato-pancreatic duct is formed by the coming together of the common bile duct and the pancreatic duct. Consequently, this serves as the common passage for the pancreatic juice and bile.
