In human anatomy, the appendix (or vermiform appendix; also cecal [or caecal] appendix; vermix; or vermiform process) is a blind ended tube connected to the cecum (or caecum).
The caecum is a pouch-like part of the colon. The appendix is near the junction of the small intestine and the large intestine. The term "vermiform" comes from Latin and means "worm-like in appearance". Its length is approximately 4 to 6 centimetres.
