cartilage rings give support to trachea to open all the time
What keeps the trachea open are small cartilage ring, called cricoid cartilage.
The trachea is a firm cartilaginous tube and is a self supporting structure
In the trachea there are rings of cartilage in a C shape

The walls of the trachea are made rigid by the presence of rings of cartilage. These rings extend from the larynx to the bronchial tubes.
The trachea is bolstered by cartilage tissue, which prevents it from collapsing.
trachea has cartilage rings which it open all the time
