Drinking
Ingestion of water or other liquids / From Wikipedia, the free encyclopedia
This article is about the act of drinking a liquid in general. For the drinking of alcohol, see Alcoholic beverage.
Drinking is the act of ingesting water or other liquids into the body through the mouth, proboscis, or elsewhere. Humans drink by swallowing, completed by peristalsis in the esophagus. The physiological processes of drinking vary widely among other animals.

Most animals drink water to maintain bodily hydration, although many can survive on the water gained from their food. Water is required for many physiological processes. Both inadequate and (less commonly) excessive water intake are associated with health problems.
