The heart is located in which thoracic subcavity?

Explanation:
The heart sits inside the pericardial cavity, the space between the layers of the pericardium that surrounds the heart. This cavity is within the thoracic cavity’s central compartment, the mediastinum. The pleural cavities are the spaces around the lungs, the abdominopelvic cavity lies below the diaphragm, and while the heart resides in the mediastinum, the pericardial cavity is the specific subcavity that contains the heart.
