*The cranial portion of the rectum is attached to the dorsal body wall by a short mesorectum which is a continuation of the mesocolon.

*The mesorectum is reflected to continue with the parietal [[Peritoneal Cavity - Anatomy & Physiology|peritoneum]] of the pelvic cavity and to cover the [[Urogenital System - Anatomy & Physiology|urogenital organs]] ventrally.

**This forms the '''rectogenital pouch'''.
