Which cavity is the location for the sigmoid colon when it reaches the pelvic region?

Explanation:
The sigmoid colon, as it descends toward the pelvis, sits in the pelvic cavity. The abdominopelvic cavity is divided into the abdominal and pelvic parts, and the sigmoid colon forms an S-shaped loop that moves from the abdominal area into the pelvic cavity as it approaches the rectum. So, in the pelvic region, its location is the pelvic cavity, not the thoracic, cranial, or abdominal regions.
