bronchi
The voicebox
larynx

Larynx → Trachea → Bronchi → Bronchioles → Alveolar sacs
Which condition is characterized by a buildup of fluid in the alveoli?
Pneumonia
What is the function of the bronchioles?
Conduct air to and from the alveoli
What is the medical term for difficult or labored breathing?
