What does ingestion refer to in exposure terminology?

Explanation:
Ingestion is the route where a chemical enters the body by swallowing it, typically through food, drink, or hand-to-mouth transfer, so it goes into the gastrointestinal tract. This is different from inhalation (breathing contaminated air) and dermal exposure (absorption through the skin). Even exposure that involves the skin or a break in the skin is considered dermal/percutaneous exposure, not ingestion, since it does not involve swallowing the substance.
