Why do the walls of the trachea do not collapse because they contain?
The walls of trachea contain c-shaped rings or cartilagenous rings.These soft bones provide rigidity to the trachea , that is why the walls of trachea doesn't collapse when there is less air.
What happens to the shape of the trachea when you swallow a large mouthful of food?
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.
Why is human trachea reinforced with cartilaginous rings are they incomplete posteriorly?
The trachea is reinforced with cartilaginous rings in order to retain the shape while breathing and the rings are incomplete to allow the trachea to expand and move when food passes through the esophagus and while bending the neck.

Why are the cartilages forming the trachea c-shaped?
The cartilage rings in the trachea need to be C shaped so large masses of food can pass through the esophagus during swallowing and large masses of air can pass through the trachea.To allow the oesophagus to expand so that large pieces of food are able to move down into the stomach without getting stuck and tearing the walls of the oesophagus.
