Which cavity contains the intestines?

The intestines are primarily located within the abdominal cavity. This cavity houses many vital organs involved in digestion and is specifically designed to protect and support the stomach and intestines. The abdominal cavity is bounded by the diaphragm at the top, and extends down to the pelvic cavity. It provides a spacious area for the intestines to function properly as they process food and absorb nutrients.

In contrast, the dorsal cavity primarily contains the brain and spinal cord, which are encased in the skull and vertebral column respectively. The thoracic cavity is located above the abdominal cavity and contains the lungs and heart, but does not contain the intestines. The pelvic cavity, while it does include some parts of the intestines, is more associated with reproductive organs and the lower parts of the digestive system, particularly the rectum. Therefore, the abdominal cavity is the most accurate choice for containing the intestines.
