Which cavity contains the small intestines?

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

Answer: (C)

The main idea is which body cavity houses the digestive organs. The small intestine sits primarily in the abdominal cavity, which contains most of the digestive tract along with organs like the stomach, liver, and spleen. The abdominal cavity is bounded above by the diaphragm and below by the pelvic brim. While a few loops of the small intestine can dip toward the pelvic area, the majority and functional location of the small intestine is within the abdominal cavity. The other cavities—cranial (brain), thoracic (heart and lungs), and pelvic (lower urinary and reproductive organs plus part of the large intestine)—do not host the primary location of the small intestine.
