The Diaphragm Between Two Cavities
Captions available
The idea
The diaphragm is a dome-shaped muscle at the base of the lungs that separates the thoracic cavity from the abdominopelvic cavity.
In practice
It forms the floor of the thoracic cavity; the aorta passes through it on its way from the chest into the abdomen.
Where people slip
Because it borders both cavities, work in the upper abdomen happens close to the chest, and the reverse.
