How and where is the appendix connected to the intestines?

The appendix is attached to the iio-caecol junction where the small intestine meets the large intestine.

The appendix is a tiny vestigial organ located at the connection between the small intestine and large intestine. The last section of the small intestine is called the ileum and the beginning if the colon or large intestine is the caecum. This junction is called the ilio-caecol junction.
