The pelvic cavity is a subdivision of which larger body cavity?

• A. Abdominopelvic cavity
• B. Abdominal cavity
• C. Thoracic cavity
• D. Dorsal cavity

Answer: (A)

The pelvic cavity is part of the abdominopelvic cavity, a single continuous space within the ventral (front) body cavity that includes both the abdominal and pelvic regions. The abdominal cavity contains organs like the stomach and intestines, while the pelvic cavity contains the bladder and reproductive organs; together they form one larger cavity. The thoracic cavity sits above the diaphragm and is separate, and the dorsal cavity is the back-side space that includes the cranial and spinal areas, not the ventral portion that contains the abdomen and pelvis. The abdominal cavity alone does not encompass the pelvic organs, so it isn’t the larger cavity that contains the pelvis.
