The rings are to keep the trachea open but they are not complete posteriorly because the esophagus runs there. The soft space allows the esophagus to fully expand when food is passed down to the stomach.
trachea
Trachea is bounded by c-shaped ring to provide it support and flexibility
Scapulas
The tissue that forms the larynx is known as the Hyaline Cartilage.
The C rings found in the trachea are made of hyaline cartridge. There are sixteen to twenty in number. Each forms a semicircular ring of hyaline cartilage, which occupies the anterior two-thirds of the trachea. The posterior one-third is filled in fibrous tissue and smooth muscle fibers.
The cartilaginous rings in a pigs trachea are incomplete. These rings are responsible for supporting the trachea of the pig when it breathes in and out. Without these rings the pig would be in danger of having their throat collapse.
The ring shape is to prevent the trachea from callapsing on itself
The trachea (or windpipe) is just a hollow tube that is anterior to your esophagus that allows air to pass from your mouth to your lungs. It functions by staying open and unobstructed with help from the epiglottis and the "C" shaped cartilage that lines the trachea.
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.
Trachea has a C-shaped cartilaginous ring.

The function of the cartilaginous rings in pigs is to provide adequate support for the trachea. Without the cartilaginous ring the pig would be in danger of their throat collapsing when the animal inhales and exhales.
Trachea is bounded by c-shaped ring to provide it support and flexibility
What keeps the trachea open are small cartilage ring, called cricoid cartilage.
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:they give support and strength to the tracheathey prevent from collapsing and breakingalso cartilage contain much collagen fibres which are stress resistantthey don't allow the trachea to shrink
beause it is the tube for going food
i dont no the trachea is located just below the pharynx. when we breath the air enters the pharynx, the trachea, the bronchus,the bionchioles, the alveolus and finally enters th lungs so the trachea moves air into the bronchus.The trachea is made up of ring of cartillage which keep the trachea opened when we inspire and expire
