Here's the breakdown of where amylase comes from:

* Salivary Amylase: Produced by the salivary glands in your mouth. This is the first step in carbohydrate digestion.

* Pancreatic Amylase: Produced by the pancreas, which releases it into the small intestine. This is the main source of amylase for breaking down carbohydrates in the body.

So, while amylase is a substance, it's not produced by a physical process like a machine, but rather by living cells within specific organs in your body.
