ANATOMY

Detailed explanation-1: -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.

Detailed explanation-2: -Bronchopulmonary segment The segmental bronchi divide into many smaller bronchioles that divide into terminal bronchioles, and then into respiratory bronchioles, which divide into 2 to 11 alveolar ducts.

Detailed explanation-3: -From the windpipe, air moves into the lungs through tubes called bronchi. The bronchi lead to smaller tubes called bronchioles, which look like the branches of a tree.

Detailed explanation-4: -Your trachea divides into your left and right bronchi. The bronchi carry air into your lungs. At the end of the bronchi, the bronchioles carry air to small sacs in your lungs called alveoli.

Detailed explanation-5: -Your bronchioles are some of the smallest airways in your lungs. Inhaled air passes through tiny ducts from the bronchioles into elastic air sacs (alveoli).
