So they don't collapse when the pressure drops.
the trachea is supported in stiff catilage to hold it together without cartilage rings it would simply fall apart.
You are thinking of the trachea, or windpipe, though it is not entirely made of cartilage.
So it doesn't collapse when you breathe. =]
The trachea is a passage that enables air to travel between the Oral and Nasal cavities into the Bronchus, in order to reach the lungs. The trachea is supported by cartilage that keeps it open, however the rings are not complete (except for the Cricoid Cartilage) which allows for flexibility.
It is made up of rings of cartillage
it helps to prevent trachea from collapsing by maintaining definite shape

The trachea is a firm cartilaginous tube and is a self supporting structure
The trachea is supported by C-shaped rings of cartilage. The point at which there is no cartilage is where the trachea is in contact with the oesophagus. As a large bolus of food passes down the oesophagus the elastic walls expand to accommodate it. This is made possible by the absence of cartilage on the trachea. However, the trachea is prevented from collapsing due to the supporting cartilage around the rest of it.
The hyaline cartilage provide support to prevent it from collapsing..im pretty sure they're also called "Rings of Cartilage"Trachea does not collapse even when there is no air in it because it is supported by rings of soft bones alled cartilage rings.
You are thinking of the trachea, or windpipe, though it is not entirely made of cartilage.
the cartilage is important because it open trachea all the time.
The C-shaped cartilage rings surrounding the trachea act as a support system, and allow the trachea to remain opened and prevent collapse with normal body movements.
cartilage rings give support to trachea to open all the time
Cartilage is necessary in the wall of the trachea because it supports the trachea and keeps it open at all times. New born babies do not have these rings of cartilage around their trachea, which is why their heads need to always be supported carefully.
What keeps the trachea open are small cartilage ring, called cricoid cartilage.
In the trachea there are rings of cartilage in a C shape
