Cartilage is a strong but flexible tissue.
The C-shaped cartilages are placed on each other but are open at the area where the trachea is nearest to the oesophagus.
They prevent and protect the traechae from collapsing during absence of air.
It also helps the traechae to expand when a person breathes.
