The diaphragm can be thought of as a sheet of muscle that separates the thoracic cavity from the abdominal cavity. When the diaphragm is relaxed, the abdominal organs push it up into a dome-like shape and the person exhales. When the diaphragm contracts, it pulls downward and the person inhales.
The diaphragm and the thoracic cavity are not the same thing.

The thoracic cavity is separated from the abdominal cavity by the diaphragm. The thoracic inlet is the upper limit of the thoracic cavity, formed by the manubrium in front, the first ribs laterally and the spine posteriorly.
