Cartilage in the respiratory system (usually found in the trachea and some small amounts in the bronchi), is to act as a way to keep the passageways open.
THE BRONCHIOLES
the bronchioles
No, the alveolar duct does not have cartilage. It is a structure within the lungs that connects the respiratory bronchioles to the alveolar sacs where gas exchange occurs. Cartilage is primarily found in the larger airways of the respiratory system to provide structural support and maintain airway patency.
The cartilage is found between all joints
bronchials
epiglottis
Cartilage is found in adults in areas such as the nose, outer ear, joints, and respiratory tract. It provides structure and support to these areas of the body.
Cartilage is a tough, flexible connective tissue that is present in the walls of the respiratory system, such as the trachea and bronchi. It provides structural support and helps to keep the airways open during breathing.

The lungs. The bronchioles are the first airway branches that no longer contain cartilage. They are branches of the bronchi, and are smaller than one millimeter. http://en.wikipedia.org/wiki/Bronchiole The lungs are in the respiratory system. They are used in the processing of oxygen in the body. The bronchioles are the first airway branches that no longer contain cartilage. They are branches of the bronchi, and are smaller than one millimeter.
