What are some functions of the cartilages in the human body?
Cartilages are responsible for the structural support of the nose and ears. The trachea and the bronchi 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 gradually substituted by the osseous tissue.
