Which two secretions mix together at the hepatopancreatic ampulla?
A
Intestinal juice and saliva
B
Saliva and gastric juice
C
Gastric juice and bile
D
Bile and pancreatic juice
Verified step by step guidance1
Understand the anatomy of the hepatopancreatic ampulla: It is a small cavity where the common bile duct and the pancreatic duct merge before emptying their contents into the duodenum.
Identify the secretions involved: The common bile duct carries bile, which is produced by the liver and stored in the gallbladder, while the pancreatic duct carries pancreatic juice, which is produced by the pancreas.
Recognize the function of bile: Bile aids in the emulsification and digestion of fats by breaking them into smaller droplets, making them easier for enzymes to act upon.
Recognize the function of pancreatic juice: Pancreatic juice contains digestive enzymes (like amylase, lipase, and proteases) and bicarbonate ions that help neutralize stomach acid and digest carbohydrates, fats, and proteins.
Conclude that at the hepatopancreatic ampulla, bile and pancreatic juice mix together before being released into the duodenum to aid in digestion.
