Tech in Surgery Prep / Unit 4 TSC 076 short lesson, about 20 seconds
The Thoracic Cavity
Captions available
The idea
The thoracic cavity is the upper part of the ventral cavity, enclosed by the rib cage and floored by the diaphragm.
In practice
It holds the two lungs, each in its own pleural cavity, and the mediastinum between them, which contains the heart.
Where people slip
Opening the chest changes how the lungs work, which is why anesthesia and the surgeon plan chest cases closely together.
