The rectum exists dorsal to the [[Reproductive System - Anatomy & Physiology|reproductive organs]], [[Urinary System Overview - Anatomy & Physiology|bladder]] and [[Urethra - Anatomy & Physiology|urethra]]. 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 [[Urinary System Overview - Anatomy & Physiology|urogenital organs]] ventrally. This forms the '''rectogenital pouch''', therefore the most distal part of the rectum is retroperitoneal. This distal, retroperitoneal part is directly attached to the [[Vagina and Vestibule - Anatomy & Physiology|vagina]] in the female and to the [[Urethra - Anatomy & Physiology|urethra]] in the male. The retroperitoneal space is filled with soft tissue rich in fat.
