Study Notes

Thoracic Cavity Structure

The thoracic cavity contains the trachea, esophagus, and other organs.
The trachea is a tube supported by 16-20 C-shaped cartilaginous rings.

Trachea Anatomy

The trachea is divided into two primary bronchi, one for each lung.
The carina is a ridge-like structure formed by the bifurcation of the trachea.
The trachea is constricted at three points:
- At its departure from the larynx
- At the level of the brachiocephalic artery
- At the point where it bifurcates into the primary bronchi, which is constricted by the arch of the aorta on the left side
