Body Cavities: Dorsal and Ventral
Captions available
The idea
A vertebrate body holds two major cavities: the dorsal cavity, housing brain and spinal cord, and the ventral cavity, housing thoracic and abdominopelvic organs.
In practice
The ventral cavity's abdominopelvic portion houses digestive and reproductive organs, distinct from its thoracic portion's heart and lungs.
Where people slip
The dorsal and ventral cavities are separate spaces — a thoracic infection does not reach the dorsal cavity directly.
