Which cavity contains the heart?

Explanation:
The heart sits in the central part of the thoracic cavity, so the concept being tested is where the heart is located within body cavities. The heart is located in the mediastinum, the central compartment of the thoracic cavity between the lungs. Inside that space it is enclosed by the pericardial sac, and the small space within that sac is the pericardial cavity that directly surrounds the heart. So the heart is within the mediastinum, with the pericardial cavity formed around it by the pericardium. The pleural cavities house the lungs, and the abdominal cavity contains abdominal organs, so those do not contain the heart.
