cecum ce·cum or cae·cum (sē'kəm)
n. pl. ce·ca (-kə)
The large blind pouch forming the beginning of the large intestine. Also called blind gut.
A saclike cavity with only one opening.
pouch or large tubelike structure in the lower abdominal cavity that receives undigested food material from the small intestine and is considered the first region of the large intestine. It is separated from the ileum (the final portion of the small intestine) by the ileocecal valve (also called Bauhin valve), which limits the rate of food passage into the cecum and may help prevent material from returning to the small intestine.
