Question

Why are caritligeneous rings present in trachea

Answer 1

Answer:

Explanation:

The trachea maintains its rigidity by virtue of a series of cartilaginous rings arranged along its length called as the C- shaped cartilage rings. They prevent the trachea from collapsing during absence of air and also protect it.

Cartilage is strong but flexible tissue.

Answer 2

Cartilaginous rings are present in trachea to prevent the collapsing of the tracheal wall in their absence of air.

The C rings of cartilage allow the esophagus to expand during swallowing, allow the trachea to change diameter during breathing, and keep the trachea patent (open).
