Explanation
The cavity bounded by the ribs and diaphragm is called the thoracic cavity, or chest cavity.

The thoracic cavity is separated from the abdominal cavity by the diaphragm, which is a thin sheet of muscle that helps to control breathing by contracting and relaxing.The thoracic cavity is essential for breathing, as it provides a protected space for the lungs to expand and contract as we inhale and exhale. It also helps to protect the heart and other vital organs from injury or damage.
