The image shows a sagittal section of the male pelvic cavity. The bladder is located anteriorly to the structure indicated by the blue arrow. This space is called the pouch of Douglas which is the inferior-most extension of the peritoneal cavity in the pelvis. In males this is located between the bladder and the rectum, so it is termed the rectovesical pouch. In females, this space lies between the vaginal canal and the rectum and is termed the rectovaginal pouch.

The image shows a sagittal section of the male pelvic cavity. The rectosigmoid junction represents the transition zone between the sigmoid colon and the rectum and it is located posterior and superior to the structure indicated by the blue arrow. The arrow points to the pouch of Douglas which is the inferior-most extension of the peritoneal cavity in the pelvis. In males this is located between the bladder and the rectum, so it is termed the rectovesical pouch.
