Which of the following is not found in the upper respiratory tract? In your lungs, the main airways (bronchi) branch off into smaller and smaller passageways the smallest, called bronchioles, lead to tiny air sacs (alveoli). Both circular and longitudinal muscles occur in the walls of the pharynx . Once inside the lungs, each bronchus is further divided into five smaller, secondary bronchi, which provide air to the lobes of the lungs. You can have lobes of your lung removed and live. smallest respiratory passageways: bronchioles: food passageway posterior to the trachea: esophagus: closes off the larynx during swallowing: . 1200mL a. oropharynx b. laryngopharynx c. nasopharynx.

Become a Study.com member to unlock this answer! Inside the lungs are bronchitubes that run from the trachea into each lung. Place the following structures in order that air passes through to reach the alveoli: alveolar ducts, alveoli, bronchioles, lobar bronchi, main bronchi, respiratory bronchioles, segmental bronchi, smaller bronchi, terminal bronchioles, and trachea. The inner walls of the alveoli are lined with a thin layer of water and surfactant, known as the pulmonary surfactant, a protein-lipid mixture secreted by type II alveolar cells [36].
