4. Stomach

Explanation:

• The mouth and the stomach are both sites of mechanical and chemical digestion of food.

Digestion in the Mouth:

• In the mouth, the teeth grind and mash the food into smaller pieces that aid in proper digestion.
• Saliva produced in the mouth contains the carbohydrate digesting enzyme, salivary amylase.

Digestion in the Stomach:

• In the stomach, protein is mainly digested by the combined action of low pH, protease enzymes like pepsin and the contraction of the muscles of the stomach.
• Pepsin breaks down protein in the presence of stomach acids.
• The muscles of the stomach contract and relax and aid in mixing the enzymes and acid together, consequently, aiding in digestion.
