Answer:

The tracheal cartilages help support the trachea while still allowing it to move and flex during breathing.

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. These rings stabilise the trachea and keep it rigid, while allowing the trachea to expand in length when the person breathes.

Cartilage is strong but flexible tissue. There are generally 16 to 20 individual cartilages. These C-shaped cartilages are stacked one on top of the other and are open at the area where the trachea is nearest to the oesophagus.
