Final answer:
Intestinal juice combines with pancreatic juice to aid digestion and absorption of nutrients in the small intestine.
Step-by-step explanation:
The juices that go into the small intestine and help digest the food are called intestinal juice. Intestinal juice is a mixture of water and mucus that aids in the absorption of nutrients from the chyme.
Intestinal juice combines with pancreatic juice, which contains enzymes and bicarbonate ions, to provide a liquid medium that facilitates absorption. The pancreatic juice also buffers the acidic gastric juice from the stomach, inactivates pepsin, and enables the optimal functioning of digestive enzymes in the small intestine.
Overall, the production and secretion of intestinal juice and pancreatic juice are essential for effective digestion and nutrient absorption in the small intestine.
