bronchioles
The trachea branches into the left and right main bronchi, which further divide into smaller bronchi within the lungs. These smaller bronchi continue to branch into bronchioles, which eventually lead to alveoli where gas exchange occurs.

bronchi
The bronchial tree, comprised of bronchi and bronchioles, divides into smaller and similar tubes resembling a tree's branches. This branching pattern allows air to reach the alveoli in the lungs efficiently for gas exchange.
The branches of the trachea are called bronchi. The trachea divides into the left and right primary bronchi, which further branch into secondary (lobar) bronchi and then into tertiary (segmental) bronchi within the lungs. This branching network continues to divide into smaller bronchioles, which lead to the alveoli where gas exchange occurs.
Trachea branches to the mainstem bronchus branches to the lobar bronchi branches to the segmental bronchi to the bronchioles branches to the terminal bronchioles branches to the respiratory bronchioles branches to the the alveolar ducts finally lead to the alveoli.Or... Trachea to Bronchus (Bronchi) to the bronchioles to the alveolar ducts to the alveoli.
The first branches off the trachea are called the bronchi. The trachea divides into two primary bronchi, which further branch out into smaller bronchioles within the lungs.

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.
