The mouth aids in food digestion through mechanical and chemical processes. Villi and microvilli in the small intestine enhance nutrient absorption, while helpful bacteria in the large intestine assist in digestion.

Explanation:

The mouth helps digest food through mechanical breakdown by chewing and chemical breakdown by the action of the enzyme amylase in saliva. Villi and microvilli in the small intestine increase the surface area for absorption and help absorb nutrients efficiently. Helpful bacteria in the large intestine aid in the digestion of certain carbohydrates and produce certain important nutrients.
