What are the organs involved in digestion together with their specific functions?

The organs involved in digestion include the mouth, stomach, small intestine, and large intestine. The mouth mechanically breaks down food and mixes it with saliva, which contains enzymes for initial carbohydrate digestion. The stomach further breaks down food using gastric juices, including acid and enzymes, to digest proteins. The small intestine is the primary site for nutrient absorption, where enzymes from the pancreas and bile from the liver help digest fats, carbohydrates, and proteins, while the large intestine absorbs water and forms waste.
