Which cavity is the space that contains the lungs and heart?

Explanation:
The chest’s main cavity for the organs of respiration and circulation is the thoracic cavity. The lungs sit inside the thoracic cavity within their own pleural sacs, and the heart lies in the central area of the chest called the mediastinum, within the pericardial cavity, which is also inside the thoracic cavity. So, the thoracic cavity is the space that contains both lungs and heart. The abdominal and pelvic cavities are lower in the trunk and don’t house these chest organs, and the pleural cavities are just the spaces surrounding the lungs, not the region that includes the heart.
