Study Notes
- The bronchi divide into smaller bronchi, then into even smaller tubes called bronchioles.
- At the end of each bronchiole are tiny air sacs called alveoli, where oxygen and carbon dioxide exchange occurs.
- Each person has hundreds of millions of alveoli in their lungs.
- The network of alveoli, bronchioles, and bronchi is known as the bronchial tree.
- The lungs contain elastic tissue, which allows them to inflate and deflate easily.
- Lungs have a thin lining called the pleura.
- The thorax is the airtight box that houses the bronchial tree, lungs, heart, and other structures.
- The top and sides of the thorax are formed by the ribs and muscles.
- Chest walls form a protective cage around the organs in the chest cavity.
- The bottom of the chest cavity is formed by the diaphragm.
