Ampulla of Vater

 The ampulla of Vater is one of the various organs in the human body which plays an important role in acting as a passage for the secretions. Ampulla of Vater is a small opening that is present at the beginning of the small intestine.

It is a point where the bile and pancreatic ducts release the secretions into the small intestine. Ampulla of Vater can also be referred to as hepatopancreatic ampulla or hepatopancreatic duct. It is situated in the major duodenal papilla present in the duodenum.

The major duodenal papilla consists of pancreatic duct opening, which ends in the duodenum. It is situated in the second part of the duodenum at a distance of 7 to 10 cm from the pylorus. The sphincter of Oddi is a section made of the muscles situated in the section of digestion organs. It helps in the movement of the juices from the pancreas to the duodenum.

The sphincter of Oddi is different from the ampulla of Vater. The sphincter of Oddi is neighboured by the ampulla of Vater. It is in a mucosal fold. It sends substances from the pancreatic and bile duct. There is also a minor duodenal papilla. It is only present in cats. Cats stick with the accessory of pancreatic ducts. The major duodenal papilla receives the bile duct.

The meaning of the word ampulla comes from the Latin word flask. The ampulla flask was used by ancient Romans to store ointments, perfume, and wine. It also refers to a sac-like enlargement of a canal or duct in the living being. There is also another organ which is also known as the ampulla of ductus deferens. It is present only in the male reproductive system. The main function of the ampulla is to act as storage chambers for semen and contributes to the secretion of semen through ejaculation. It is thinner than the rest of the sperm canal. The thinness varies with different living species.

The term, “Ampulla of Vater” was named after the German anatomist Abraham Vater (1648-1751). He published a description of it in the year 1720.
