Document Summary

Digestive system: digestion is the mechanical and chemical breakdown of foods and the resulting absorption of nutrients by cells, mechanical digestion breaks large pieces of food into smaller ones without altering their chemical composition, chemical digestion breaks food into simpler chemicals, which get absorbed into the body for further use, the digestive system consists of the alimentary canal, which extends from the mouth to the anus, and several accessory organs, which secrete substances into the canal, used in digestion, process food for energy as a source of materials for growth and repair. Mouth: teeth, which break up food for mechanical digestion, tongue, which mixes and shapes food into a ball to aid in swallowing, salivary glands produce enzyme amylase to help break down starch, function of the mouth: mechanical digestion: breaks up food and mixes it with saliva, chemical digestion: amylase hydrolyzes starch into the disaccharide maltose.
