The heart is located in which body cavity?

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

Answer: (C)

The heart sits in the chest, inside the thoracic cavity. This cavity is the space within the rib cage and above the diaphragm, housing the heart and lungs. The heart itself lies in the mediastinum, protected by the pericardial sac that surrounds it. The other cavities listed aren’t where the heart is: the cranial cavity is inside the skull and contains the brain; the abdominal cavity holds organs like the stomach and intestines; the pelvic cavity contains pelvic organs. The diaphragm forms the boundary between the thoracic and abdominal cavities, keeping the heart in the chest.
