The respiratory tree consists of several key parts, including the trachea, which branches into the primary bronchi, leading to the secondary (lobar) bronchi, and further into the tertiary (segmental) bronchi. These bronchi continue to divide into smaller bronchioles, which eventually lead to the alveolar ducts and alveoli, where gas exchange occurs. The entire structure facilitates the movement of air into and out of the lungs while also serving to filter, warm, and humidify the air.

What are the parts of the respiratory tree to which the aleoli are attached?

The alveoli are attached to the terminal bronchioles, which branch from the respiratory bronchioles in the respiratory tree. These structures are part of the lower respiratory tract, where gas exchange occurs. The alveoli are small, balloon-like sacs at the end of the bronchial tree, surrounded by capillaries, facilitating the exchange of oxygen and carbon dioxide.
