Who Do Bronchi Do?

Your bronchi carry air to and from your lungs. The bronchi also help moisturize the air you breathe and screen out foreign particles. Your airways are lined with cells that create mucus. The mucus keeps your airways moist.

Where do bronchi lead to?

In your lungs, the main airways (bronchi) branch off into smaller and smaller passageways — the smallest, called bronchioles, lead to tiny air sacs (alveoli).

What is the role of the bronchioles in the respiratory system?

The bronchi, bronchioles, and terminal bronchioles are a series of branching airways that represent the conducting system for air to travel from the trachea to the alveolar ducts and alveoli where gas exchange occurs.
