Answer:

The function of the cartilaginous rings of the trachea in respiratory system is to stabilize the trachea and keep it rigid while allowing the trachea to expand and lengthen when the person breathes.

Explanation:

The cartilage rings are C-shaped because the back of the trachea presses against the esophagus. The cartilage opens at the esophagus and is replaced by connective tissue and muscle. This gives the esophagus space to allow food to be swallowed easily.

The first and last tracheal rings are broader and deeper than the others. The first ring is just beneath the larynx and the thyroid gland. The last one is just above where the trachea branches off into the bronchi, the two tubes that lead to the lungs. (Wikipedia)
