The ampulla of Vater (latin: papilla Vateri, papilla duodeni major), also known as the hepatopancreatic ampulla, is formed by the union of the pancreatic duct and the common bile duct. Gray's Anatomy the Respiratory apparatus ( Apparatus Respiratorius Respiratory system Respiratory apparatus Medical Subject Headings ( MeSH) is a huge Controlled vocabulary (or metadata system for the purpose of indexing journal articles and books Elsevier, the world's largest Publisher of Medical and Scientific literature, forms part of the Reed Elsevier group The pancreatic duct, or duct of Wirsung, is a duct joining the Pancreas to the Common bile duct to supply pancreatic juices which aid in Digestion Bile, which is synthesized in the liver is carried to the right and left hepatic ducts which converge along with the Cystic duct to form the Common hepatic duct. The ampulla is specifically located at the major duodenal papilla. The Common bile duct and the Pancreatic duct together perforate the medial side of the second portion of the Duodenum obliquely some 7 to 10 cm below the Pylorus
One important thing to note about the Ampulla of Vater is that its entrance point, halfway along the second part of the duodenum, marks the anatomical transition from foregut to midgut (and hence the point where the celiac trunk stops supplying the gut and the superior mesenteric artery takes over).

Function
Various smooth muscle sphincters regulate the flow of bile and pancreatic juice through the ampulla: the sphincter of the pancreatic duct, the sphincter of the bile duct, and the hepatopancreatic sphincter (Sphincter of Oddi). Smooth muscle is a type of non- Striated muscle, found within the Tunica media layer of large and small Arteries and Veins, the bladder A sphincter is a structure usually a circular Muscle, that normally maintains constriction of a natural body passage or orifice and which relaxes as required by normal physiological Bile or gall is a bitter yellow or green Alkaline fluid secreted by Hepatocytes from the Liver of most Vertebrates In many species Pancreatic juice is a juice produced by the Pancreas. It contains a variety of Enzymes, including Trypsinogen, Chymotrypsinogen, Elastase The Sphincter of Oddi, also called the hepatopancreatic sphincter or Glisson's sphincter, controls secretions from the Liver, Pancreas, and The Sphincter of Oddi, also called the hepatopancreatic sphincter or Glisson's sphincter, controls secretions from the Liver, Pancreas, and
The Sphincter of Oddi controls the introduction of bile and pancreatic secretions into the duodenum, as well as preventing the entry of duodenal contents into the Ampulla. The Sphincter of Oddi, also called the hepatopancreatic sphincter or Glisson's sphincter, controls secretions from the Liver, Pancreas, and
Related disorders
- Pancreatitis can result from a failure of pancreatic secretions to drain properly. Pancreatitis is the Inflammation of the Pancreas. See also Acute pancreatitis and Chronic pancreatitis for more details One possible cause of impaired drainage of pancreatic juice is blockage of the hepatopancreatic ampulla. The ampulla of Vater (papilla Vateri papilla duodeni major also known as the la hepatopancreatic ampulla, is formed by the union of the Pancreatic duct and A common culprit to cause blockage is a gallstone in the common bile duct. In Medicine, gallstones (choleliths are Crystalline bodies formed within the body by accretion or concretion of normal or abnormal Bile component Bile, which is synthesized in the liver is carried to the right and left hepatic ducts which converge along with the Cystic duct to form the Common hepatic duct.
