trachea --> bronchi -->bronchioles --> alveoli
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.
respiratory bronchioles, alveolar ducts and 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 smallest branches of the bronchial tree in a cat are bronchioles. These bronchioles are responsible for conducting air to and from the alveoli, where gas exchange occurs.
These small sac like structure are known as the alveoli . The alveoli help in the exchange of the gases, oxygen & carbon-dioxide,Lungs contain alveoli to increase the surface area and to easily transport oxygen to the blood vessels which surrounds the air sacs. Also, the air sacs have a thin film of oxygen which helps to absorb oxygen quickly.
the center part of the tree is called the core.
