Final answer:
The ductile cells in the pancreas secrete "pancreatic juice" into the blood and exchange "digestive enzymes" for "neutralizing acidic chyme".
Step-by-step explanation:
The ductile cells in the pancreas secrete pancreatic juice into the blood and exchange digestive enzymes for neutralizing acidic chyme. These ductile cells are part of the exocrine function of the pancreas and are responsible for producing and releasing digestive enzymes that aid in the breakdown of carbohydrates, proteins, lipids, and nucleic acids in the small intestine. This secretion of pancreatic juice into the blood and exchange of enzymes for neutralization is essential for proper digestion and absorption of nutrients.
