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.
There like tree branches that branch off to the alveoli
The alveoli and bronchi are both parts of the respiratory tree. The main parts of this structure, in the order of air passing through during inspiration are: trachea, bronchi, bronchioles, and alveoli. The alveoli are distal to the bronchi, because they are farther away from the center of the body then the bronchi.
In the Bunch of Grapes model, each grape represents an alveolus in the lungs where gas exchange occurs. The stem of the grape bunch represents the bronchioles that lead to the alveoli. The vine represents the bronchial tree, including the bronchi and bronchioles that transport air to the alveoli.
An alveolus (plural: alveoli, from Latin alveolus, "little cavity") is an anatomical structure that has the form of a hollow cavity. Found in the lung parenchyma, the pulmonary alveoli are the dead ends of the respiratory tree, which outcrop from either alveolar sacs or alveolar ducts, which are both sites of gas exchange with the blood as well.
The alveoli are at the end of the respiratory tree and is where oxygen and carbon dioxide are exchanged between the lungs and the blood.
The respiratory zone of the tracheobronchial tree includes the respiratory bronchioles, alveolar ducts, alveolar sacs, and alveoli where gas exchange occurs. This is where oxygen is absorbed into the bloodstream and carbon dioxide is released from the bloodstream.

The smallest branches of the bronchial tree in a cat are bronchioles.
the center part of the tree is called the core.
