Answer :
Final answer:
In the cephalic phase, the secretion of pancreatic juice is controlled by neural signals originating from the brain. These signals stimulate the release of pancreatic juice, which contains enzymes that aid in the digestion of carbohydrates, proteins, and fats.
Explanation:
In the cephalic phase, the secretion of pancreatic juice is controlled by neural signals originating from the brain. This phase is triggered when we see, smell, taste, or even think about food. The brain sends signals to the pancreas through the vagus nerve, which stimulates the release of pancreatic juice.
Pancreatic juice is a mixture of enzymes, electrolytes, and water that aids in the digestion of carbohydrates, proteins, and fats. The enzymes present in pancreatic juice, such as amylase, lipase, and trypsin, play a crucial role in breaking down food molecules into smaller units that can be absorbed by the body.
Overall, the cephalic phase is the initial phase of digestion and prepares the body for food intake. It ensures that the pancreas releases pancreatic juice to assist in the digestion process.
