Medical Assistant Prep / Unit 2 MAS 034 short lesson, about 20 seconds
The Body's Cavities
Captions available
The idea
The internal organs sit in two main cavities: a larger ventral cavity in front and a smaller dorsal cavity behind.
In practice
The diaphragm splits the ventral cavity into the thoracic cavity, holding heart and lungs, and the abdominopelvic cavity below; the dorsal cavity holds the brain and spinal cord.
Where people slip
The diaphragm is a wall, so chest and abdomen are separate compartments.
