When you're dissecting the gas exchange system, it's important to understand where everything is.
- The trachea should be visible without making any incisions in the lungs.
- It is the tube running into the lungs surrounded by C-shaped cartilage rings.
The trachea splits into two bronchi.
- Once you continue to cut down the trachea and into the bronchi, it branches into smaller branches over the lungs.
- These smaller branches are called bronchioles.
