Verified step by step guidance

Understand the role of amylase: Amylase is an enzyme responsible for breaking down starch into simpler sugars, such as maltose and glucose. It is produced by specific organs involved in digestion.

Identify the sources of amylase: Amylase is primarily secreted by the salivary glands (salivary amylase) and the pancreas (pancreatic amylase). These organs play a direct role in the digestion of carbohydrates.

Evaluate the small intestine (mucosa): While the small intestine is involved in digestion and absorption, it does not produce amylase. Instead, it produces other enzymes like maltase, sucrase, and lactase to further break down sugars.

Consider the liver: The liver is a vital organ with many functions, including detoxification, bile production, and metabolism. However, it does not produce amylase or directly participate in carbohydrate digestion.

Conclude which organ is NOT a source of amylase: Based on the information above, the liver is not a source of amylase, making it the correct answer to the question.
