The Waist Line corresponds to which body cavity?

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

Answer: (A)

Cavities are organized by location, and the waist line sits in the abdomen. The abdominal cavity runs from the diaphragm down to the pelvic brim and contains most digestive organs and related structures. The thoracic cavity lies in the chest above the diaphragm, the pelvic cavity is lower in the pelvis, and the cranial cavity is inside the skull. If you’re thinking of the broader region, sometimes people refer to the abdominopelvic cavity, but the waist line specifically corresponds to the abdominal cavity.
