Verified step by step guidance

Understand the role of each organ in the digestive system: The mouth, stomach, small intestine, and pancreas all have specific functions in digestion.

Identify the primary function of the mouth: The mouth is responsible for mechanical digestion through chewing and chemical digestion of carbohydrates via salivary amylase, but it does not produce enzymes that digest proteins.

Examine the role of the stomach: The stomach secretes pepsin, an enzyme that begins the digestion of proteins into smaller peptides.

Consider the function of the small intestine: The small intestine continues protein digestion with enzymes like trypsin and chymotrypsin, which are secreted by the pancreas and activated in the small intestine.

Review the role of the pancreas: The pancreas produces digestive enzymes, including those that break down proteins, which are released into the small intestine.
