Body Cavities
Captions available
The idea
The body has two main cavities: a posterior, or dorsal, cavity and an anterior, or ventral, cavity.
In practice
The dorsal cavity holds the brain and spinal cord; the ventral cavity holds the thoracic cavity above the diaphragm and the abdominopelvic cavity below it.
Where people slip
The heart lies in the mediastinum, the central part of the thoracic cavity, between the lungs.
