Salivary digestion, also known as oral digestion, refers to the mechanical and chemical breakdown of food that occurs in the mouth. Synonyms for salivary digestion may include oral processing, mastication, chewing and initial digestion. The process involves the secretion of saliva, which contains enzymes like salivary amylase that begins the digestion of carbohydrates in food. Other enzymes found in saliva, such as lingual lipase and lysozyme, contribute to the breakdown of lipids and proteins respectively. Ultimately, salivary digestion prepares the food for further digestion in the stomach and small intestine. In summary, salivary digestion is an essential initial step in the overall process of digestion and nutrient absorption.
