Detailed explanation-1: -You have two main bronchi in your right and left lungs that divide and branch off into smaller segments, like tree branches. At the end of your bronchi, the alveoli exchange oxygen and carbon dioxide.

Detailed explanation-2: -There are 20-25 branching generations of conducting bronchioles after the tertiary segmental bronchi. As the bronchioles become smaller in width, they become terminal bronchioles which mark the end of the conducting zone of the respiratory system.

Detailed explanation-3: -In your lungs, the main airways, called bronchi, branch off into smaller and smaller passageways. The smallest airways, called bronchioles, lead to tiny air sacs called alveoli.
