A bronchiole has no cartilage in its wall, a bronchus does.

I belive it's a mixture of cartilage and lung tissue containing cila.
That tube is called the trachea. It is also known as the windpipe.
A terminal bronchiole is a small airway that marks the end of the conducting zone in the respiratory system. It is lined with simple cuboidal epithelium and surrounded by smooth muscle. The terminal bronchiole branches into alveolar sacs, which are clusters of alveoli where gas exchange occurs. Alveolar sacs have thin walls composed of simple squamous epithelium and are surrounded by a network of capillaries.
Terminal bronchioles do not have cartilage in their walls.
Air enters the external nares, passes through the nasal cavity, travels down the pharynx, enters the larynx, moves through the trachea and bronchi, and finally reaches the alveoli in the lungs where gas exchange occurs.
The three types of bronchioles are terminal bronchioles, respiratory bronchioles, and conducting bronchioles. Terminal bronchioles are the smallest airways in the respiratory system that lead to the respiratory bronchioles where gas exchange occurs. Conducting bronchioles are larger airways that branch off the main bronchi and help to conduct air to the smaller bronchioles.
The order of passageways from proximal to distal in the human body is typically mouth, esophagus, stomach, small intestine (duodenum, jejunum, ileum), large intestine (cecum, colon, rectum), and anus.

Bronchiole is the medical term meaning small bronchi
The next smaller branch of the respiratory passageway after the tertiary bronchus is the bronchiole, which further divides into terminal bronchioles, respiratory bronchioles, and ultimately alveolar ducts and sacs where gas exchange occurs.
