caecum is a small blind sac which hosts some symbiotic micro organisms.
why is caecum called a blind sac ?
The cecum or caecum (from the Latin caecus meaning blind)and sac means pouch like. Therefore Ceacum is referred as blind sac. Caecum is a pouch at the junction of the small and large intestines, terminating in the appendix. It has no known function in humans.
