About Human Digestive System
The human digestive system breaks food into absorbable molecules through mechanical processing, enzyme action and chemical conditions along the alimentary canal. Questions cover the mouth, stomach, small and large intestines, liver, pancreas and associated secretions, including the digestion and absorption of carbohydrates, proteins, lipids, vitamins, minerals and water.
