Expert: JamesStone replied 5 years ago. The trachea is reinforced with cartilage rings in order to keep the airway open. These rings reinforce the anterior and lateral sides, but are actually C shaped as opposed to complete rings which allows the trachea to constrict somewhat when swallowing food.

Your trachea is essentially an air-conducting tube (commonly known as your windpipe) that connects your larynx to the rest of your respiratory system.Though the cylindrical tube is only about three-quarters of an inch in diameter and 4 to 5 inches long, you wouldn't be able to survive without it.he trachea is a rigid tube that conducts air from your larynx to your bronchi. The trachea's rigidity is maintained by a series of cartilaginous rings arranged along its length called C-shaped cartilage rings.
