Pancreatic juice secretion is regulated by the hormone secretin, which is produced by the duodenal mucosa. It is rich in bicarbonates and helps in neutralizing the acidic chyme. It also contains enzymes like amylase, lipase, and proteases.

1. Pancreatic juice is secreted by the stomach.
2. Pancreatic juice is secreted by the pancreas.
3. Pancreatic juice is secreted by the liver.

Correct answer: Pancreatic juice is secreted by the pancreas.

Pancreatic juice is made by the pancreas, not the stomach, liver, or small intestine. Secretin from the duodenum triggers the pancreas to release bicarbonate-rich juice that neutralizes acidic chyme and carries digestive enzymes.
