The cavity that contains both abdominal and pelvic cavities is called:

• A. Abdominal Cavity
• B. Pelvic Cavity
• C. Abdominopelvic Cavity
• D. Thoracic Cavity

Answer: (C)

Think of the body as organized into cavities, with the diaphragm forming a boundary between the chest and the area below. The space that holds organs from both the abdominal region (like the stomach and intestines) and the pelvic region (such as the bladder and reproductive organs) is the abdominopelvic cavity. It continues from the diaphragm down to the pelvic floor, so it includes everything in both the abdominal and pelvic areas as one continuous cavity.

That’s why the term abdominopelvic cavity is used—it reflects this combined space. The abdominal cavity alone doesn’t include the pelvic organs, the pelvic cavity alone doesn’t include most abdominal organs, and the thoracic cavity is up in the chest, containing the heart and lungs, separate from the abdominal and pelvic organs.
