Final answer:
Amylase is produced by the pancreas and salivary glands and is involved in the breakdown of carbohydrates in the digestive system.
Step-by-step explanation:
The regions of the digestive system in which amylase is produced are the pancreas and the salivary glands. The pancreas produces pancreatic juice that contains digestive enzymes including pancreatic amylase, which helps in the breakdown of carbohydrates in the small intestine. Additionally, amylase is also secreted by the salivary glands in the mouth, where it begins the digestion of carbohydrates.
