Q. What are a few functions of the cartilages in the human body?

Cartilages are responsible for the structural support of the ears and nose. The bronchi and the trachea are also organs with cartilaginous structures that prevent the closing of these tubes in joints there are cartilages that cover the bones providing a smooth surface to reduce the friction of the joint movement. In the formation of bones the cartilages act as a mold and they are slowly substituted by the osseous tissue.
