ingestasjon

Ingestasjon is the process by which a substance is taken into the body through the mouth. This can refer to the consumption of food and drink for nourishment, as well as the accidental or intentional intake of non-food items. In biological contexts, ingestasjon is the first step in the digestive process, where external materials are brought into the digestive tract.

In humans and many animals, ingestasjon is a voluntary action, driven by hunger, thirst, or social behaviors. The ingested material passes through the esophagus and into the stomach, where it begins to be broken down. The efficiency and safety of ingestasjon depend on various factors, including the physical and chemical properties of the substance and the health of the organism.

The term ingestasjon can also be used in a broader sense to describe the incorporation of particles or substances into a cell or organism. For instance, phagocytosis is a cellular process where cells engulf and ingest larger particles. In environmental science, ingestasjon might refer to the intake of contaminated materials by organisms, which can lead to toxicological effects or bioaccumulation. Accidental ingestasjon, such as swallowing small objects or toxic substances, is a concern, particularly in children.
