Entero- is a combining form used like a prefix meaning “intestine.” The intestines are the long tract of the digestive system that runs from the stomach to the anus. Entero- is often used in medical terms, especially in anatomy and pathology.

Entero- comes from the Greek énteron, meaning “intestine.” A scientific term for the digestive tract (alimentary canal) is enteron, which comes from this same Greek root. The word dysentery, literally meaning “bad bowels,” also derives from the Greek énteron.
