—Bronchi, bronchioles and alveoli - looks like an upside down tree.
◦Trachea is the main trunk that divides into
◦Right bronchus and left bronchus. As the bronchi enter the lungs they divide into smaller and smaller branches.
◦The smallest tubes whose walls are made only of smooth muscle are called bronchioles.
◦Bronchioles further divide into microscopic tubes called alveolar ducts which resemble the main stem of a bunch of grapes.
◦Alveolar ducts end in several alveolar sacs arranged like a clusters of grapes.
◦The walls of the alveolar sacs are made up of numerous alveoli each of which resembles a single grape.

How does the bronchi work?
A bronchus is a passage of airway in the respiratory tract that conducts air into the lungs. The bronchus branches into smaller tubes, which in turn become bronchioles.
What parts are in the lower respiratory tract?
The main parts of the lower respiratory tract are the trachea, two bronchial tubes, the bronchioles, and the lungs. The upper and lower respiratory tracts come together to make up the entire respiratory system.
What is the special cell that lines the tubes in the respiratory system?
Goblet cells are found in the respiratory epithelium. They produce mucous which coats the tubes. Goblet cells are found scattered among the epithelial lining of organs, such as the intestinal and respiratory tracts. They are found inside the trachea, bronchi, and larger bronchioles in the respiratory tract, small intestines, the large intestine, and conjunctiva in the upper eyelid.
What are the smallest divisions from the trachea?
