context_page_description: Ingestion is the consumption of a substance by an organism. In animals, it normally is accomplished by taking in a substance through the mouth into the gastrointestinal tract; such as through eating or drinking. In single-celled organisms ingestion takes place by absorbing a substance through the cell membrane.
  Besides nutritional items, substances that may be ingested include medication, recreational drugs, and substances considered inedible; such as foreign bodies or excrement. Ingestion is a common route taken by pathogenic organisms and poisons entering the body.
  Ingestion can also refer to a mechanism picking up something and making it enter an internal hollow of that mechanism, e.g. "a grille was fitted to prevent the pump from ingesting driftwood".
context_section_description: Disk batteries, also called button cells, are often mistakenly ingested, particularly by children and the elderly. They may be mistaken for a medication pill because of their size and shape, or they may be swallowed after being held in the mouth while the battery is being changed. Battery ingestion can cause medical problems including blocked airway, vomiting, irritability, persistent drooling, and rash (due to nickel metal allergy).
