Which of the following juice passes through the ampulla of water?
A. Succus entericus
B. Pancreatic juice
C. Bile
D. Secretion of Brunner's gland

• The common bile duct and the pancreatic duct come together to generate an ampulla of water. 
• This is positioned specifically at the largest duodenal papilla. 
• It controls the passage of the fluids and enzymes generated in the pancreatic duct and common bile duct. 
• It is also referred to as the hepatopancreatic ampulla or the hepatopancreatic duct as a result.
• The sphincters that control the passage of bile and pancreatic juice guard the ampulla of water. 
• These sphincters are: - 

The pancreatic duct sphincter
The bile duct's sphincter
The oddi sphincter

Hence, option A is the correct answer.
