What is the function of the Ampullae?
The ampullae of Lorenzini (Figures 3.15 and 3.37) are modified parts of the lateral line system (see later) and primarily sensitive to electrical fields (they can help a shark sense prey by detecting the electrical fields generated by activities of the prey).
Where is the Ampulla found?
The ampulla of Vater is a small opening that enters into the first portion of the small intestine, known as the duodenum. The ampulla of Vater is the spot where the pancreatic and bile ducts release their secretions into the intestines.
How is ampullary carcinoma diagnosed?
Endoscopic retrograde cholangiopancreatography (ERCP). A biopsy is the only way to confirm this cancer. Small tissue samples are removed and checked in a lab to find out the type of cancer cells present. After a diagnosis of ampullary cancer, you’ll likely need more tests.

They enable fish to detect electromagnetic fields in the water. This is thought to play a role in the ability of fish to detect prey, as well as changes in water temperature.
What function does the ampulla have?
In human anatomy, ampulla is defined as pertaining to the common bile duct. The common bile duct transports bile from the liver and gallbladder. Eventually the bile makes its way to the duodenum. The place where the common bile duct and the pancreatic duct meet in the major duodenal papilla is called the ampulla of Vater.
