The chest, including the heart, trachea, great vessels, is which cavity?

• A. Pleural cavity
• B. Mediastinum cavity
• C. Thoracic Cavity
• D. Abdominal Cavity

Answer: (C)

In anatomy, the chest region is the thoracic cavity. It houses the lungs, heart, trachea, and major vessels, all protected by the rib cage and diaphragm. Within the thoracic cavity there is a central compartment called the mediastinum, which specifically contains the heart, trachea, and great vessels. So the description “the chest, including the heart, trachea, and great vessels” fits the thoracic cavity as a whole. The pleural cavities are the spaces around each lung, and the abdominal cavity lies below the diaphragm, so they don’t match the full set of structures described.
