The cartilage rings in the trachea prevent the trachea from collapsing during absence of air and also protect it.
These cartilagenous ring are C shaped and are meant for particular purposes such as:
The cartilage keeps your trachea from collapsing.
Trachea contain cartilage rings, and is the long tube that goes to the lungs. The bronchi contain cartilage plates and are the branching tubes that go to the lungs.
Rings of cartilage
Cartilage in the respiratory system (usually found in the trachea and some small amounts in the bronchi), is to act as a way to keep the passageways open.
Cartilage keeps bronchi open
This is very good question. Which haunted me for decades. If you have no cartilage, then your larynx and bronchi will collapse. If you have full cartilage ring, then your bronchi can not get constricted. Incomplete rings of cartilage has solved the problem. Your bronchi and trachea do not collapse and can constrict also.
No, cartilage is only contained up until the bronchi. The bronchioles and onward do not contain any cartilage rings, only smooth muscle.
The function of the trachea is the same in all terrestrial vertebrates. It provides an airway from the mouth to the bronchi.

to support trachea
Hyaline cartilage, which also covers the ends of bones at the joints, which reduces friction during movement.
To hold something permanently open (such as the trachea, which is held open for breathing by rings of cartilage).
