Answer: Sodium bicarbonate produced by the Pancreas.
Explanation:
The mixture of partially digested food and gastric juice is called chyme. Chyme leaves the stomach through the pyloric sphincter to enter the small intestine. This is where all terminal digestion of carbohydrates, lipids, and proteins occurs, and where the products of digestions—amino acids, glucose, and so on—are absorbed into the blood. The first 25 centimeters is the duodenum; the remainder of the small intestine is divided into the jejunum and the ileum. The duodenum receives acidic chyme from the stomach, digestive enzymes, and bicarbonate from the pancreas, and bile from the liver and gallbladder. The pancreatic juice enzymes digest larger food molecules into smaller fragments.
