The urinary bladder is contained in which body cavity?

• A. Abdominal
• B. Pelvic
• C. Thoracic
• D. Cranial

Answer: (B)

The urinary bladder sits in the pelvic cavity. It lies in the true pelvis, just behind the pubic symphysis, and its position differs slightly between sexes (in males it is anterior to the rectum; in females it is anterior to the uterus and above the vagina). While a full bladder can rise toward the abdominal area, its normal and primary location is within the pelvic cavity, with most of its structure lying in the extraperitoneal space and only the superior surface briefly covered by peritoneum.
