Which respiratory structures are comprised of cartilage and ligaments?

The respiratory structures that are comprised of cartilage and ligaments include the trachea, which is supported by C-shaped rings of cartilage, and the bronchi, which also contain cartilage plates to maintain their structure. Additionally, the larynx is composed of several cartilages, including the thyroid and cricoid cartilages, and is supported by ligaments that connect these structures. These components work together to ensure the airway remains open and flexible during breathing.
