nielemätoiminnasta

Nielemätoiminta refers to the activities and processes that occur within the human digestive system, specifically in the mouth. This process begins with the ingestion of food, where it is broken down into smaller particles through the mechanical action of chewing. Chewing also initiates the chemical breakdown of food through the action of saliva, which contains enzymes like amylase that begin the digestion of carbohydrates. Saliva also helps to moisten the food, making it easier to swallow. The swallowed food then travels to the stomach, where further digestion and absorption processes will occur. Nielemätoiminta is crucial for the body's ability to extract nutrients from food and is an essential part of the overall digestive process.
