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: -Within the lungs, the bronchi branch into smaller bronchi and even smaller tubes called bronchioles (pronounced: BRAHN-kee-olz). Bronchioles end in tiny air sacs called alveoli, where the exchange of oxygen and carbon dioxide actually takes place. Each person has hundreds of millions of alveoli in their lungs.

Detailed explanation-3: -The smallest viola is, in fact, much smaller than a full-sized violin at just 30 centimetres (12 inches) long. These small violas are ideal for beginner students and children.

Detailed explanation-4: -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). The alveoli are surrounded by the alveolar-capillary membrane, which normally prevents liquid in the capillaries from entering the air sacs.

Detailed explanation-5: -The terminal bronchiole is the smallest conducting airway without alveoli in its walls. There are about 30, 000 terminal bronchioles in the lungs, and each of these, in turn, directs air to approximately 10, 000 alveoli.
