31 Οκτ 2020 · The trachea, bronchi and bronchioles form the tracheobronchial tree – a system of airways that allow passage of air into the lungs, where gas exchange occurs. These airways are located in the neck and thorax.
6 Ιουλ 2020 · Together, the trachea and the two primary bronchi are referred to as the bronchial tree. At the end of the bronchial tree lie the alveolar ducts, the alveolar sacs, and the alveoli.
A bronchial tree (or respiratory tree) is the collective term used for these multiple-branched bronchi. The main function of the bronchi, like other conducting zone structures, is to provide a passageway for air to move into and out of each lung.
30 Οκτ 2023 · Function. No gas exchange takes place in the bronchi. The conducting portion of the bronchial tree thus extends from the tracheal bifurcation to the terminal bronchiole, inclusively. The respiratory portion includes the respiratory bronchiole, alveolar ducts, alveolar sacs, and alveoli.
The tracheobronchial tree is a branching tree of airways composed of: the trachea. the bronchioles. [1] Figure 1: Lower respiratory tract. Its main function is the transfer of air from the environment to the lungs for gas exchange.

2 Ιαν 2024 · The bronchial tree begins at the bifurcation of the trachea at the carina, approximately at the level of T5. The trachea bifurcates into the main left and right bronchi, These bronchi continue to branch until they form alveoli, the site of gas exchange.
