GI tract
Food's internal highway
The GI tract is the gastrointestinal tract—the continuous tube running from mouth to anus through which food passes and is digested.
It includes the esophagus, stomach, and intestines.
Medical contexts use the term frequently: The infection spread throughout his GI tract.
Also called the digestive tract or alimentary canal.
