They're located at the end of the bronchioles which are connected to the bronchi
Bronchi is branched in primary and secondary. bronchi is branch of bronchus.
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.

Bronchi, Bronchioles and Alveoli. Bronchi and Bronchioles - transport systems Alveoli - Respiration occurs
alveoli
The bronchi branch into smaller tubes called bronchioles, which then lead to clusters of air sacs called alveoli. The alveoli are the site where oxygen and carbon dioxide exchange occurs during the process of respiration.
The trachea splits into the left and right bronchi in the thoracic cavity(the chest). From there the bronchi continue to branch out and keep getting smaller. Kind of like the branches on a tree. At the end of the those branches (bronchioles) are the alveoli( tiny grape like structures). In the alveoli is where the exchange of oxygen and carbon dioxide occur.
The branches of the bronchial tree ultimately end in the alveoli, which are tiny air sacs in the lungs. These alveoli are the sites of gas exchange, where oxygen is absorbed into the blood and carbon dioxide is released. The bronchial tree includes primary bronchi, secondary bronchi, tertiary bronchi, and smaller bronchioles, leading to these alveolar structures.

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.
