Iliac and Pelvic Colons
The iliac and pelvic colons, from a formalin-hardened male body, aged 30. The pelvic colon was usually long; its course is shown, as well as that of the beginning of the rectum, by dotted lines. It first ran across the upper surface of the bladder to the right pelvic wall, then recrossed the pelvis in a line posterior to is first crossing; finally it returned towards the middle line, and passed into the rectum. As a rule, after crossing to the right side of the pelvis, the pelvic colon turns backwards and inwards to reach the middle line, where it passes into the rectum.
