Within the thoracic cavity, the space that houses the heart is called the

Explanation:
The space that houses the heart is the pericardial cavity. The heart sits inside a two-layered membrane called the pericardium, and the pericardial cavity is the potential space between the inner visceral layer and the outer parietal layer of that membrane. This fluid-filled space reduces friction during each heartbeat as the heart moves within the mediastinum of the thorax. The pleural cavities surround the lungs, not the heart; the mediastinal area is the central chest region that contains the heart and great vessels, but the specific space around the heart is the pericardial cavity; the abdominopelvic cavity lies below the diaphragm.
