Which term refers to the region between the diaphragm and pelvis?

• A. Face
• B. Pelvis
• C. Abdomen
• D. Thorax

Answer: (C)

The region between the diaphragm and pelvis is the abdomen. The diaphragm forms its superior boundary, separating it from the thoracic cavity, while the pelvic inlet marks the inferior boundary near the pelvis. This space contains most of the digestive organs and other viscera, with its walls formed by the abdominal muscles and the lower ribs anteriorly and the spine posteriorly. The face lies in the head, the thorax is the chest above the diaphragm, and the pelvis refers to the lower part of the trunk below the abdomen, so only the abdomen fits between the diaphragm and pelvis.
