Question

compare the role of bile juice and hydrochloric acid in the process of digestion.where are they produced​

Answer 1

Digestion starts with the sight, thought, or smell of food. When the brain anticipates an incoming meal, the vagus nerve sends a message to the stomach causing the release of acetylcholine. The binding of acetylcholine to G cells in the stomach starts the secretion of gastrin and, in combination with acetylcholine and histamine, stimulates parietal cells in the gastric glands of the stomach body to start secreting hydrochloric acid (HCl).
