What is the primary function of alveoli in the lungs?
What is the primary function of alveoli in the lungs?
- To filter out pollutants from inhaled air.
- To regulate the flow of air into the bronchi.
- To facilitate the exchange of oxygen and carbon dioxide. (correct)
- To produce red blood cells.
What structural feature do bronchi share with a tree?
What structural feature do bronchi share with a tree?
- A branching pattern. (correct)
- The presence of leaves.
- A rigid trunk.
- The ability to absorb water.
How does the exchange of gases in the alveoli affect the color of red blood cells?
How does the exchange of gases in the alveoli affect the color of red blood cells?
- They turn from clear to red as they release carbon dioxide.
- They maintain a constant red color regardless of gas exchange.
- They turn from purple to red as they pick up oxygen. (correct)
- They turn from red to purple as they release oxygen.

Bronchi
Bronchi
Tubes within the lungs that branch into smaller tubes, resembling tree branches.
Alveoli
Alveoli
Tiny air sacs at the end of bronchioles in the lungs where oxygen and carbon dioxide are exchanged.
Gas Exchange

Study Notes
- Lungs are sponge-like organs containing tubes called Bronchi.
- Bronchi branch into smaller tubes, similar to tree branches.
- At the end of these tubes exist millions of tiny bubbles or sacs called alveoli.
- Alveoli facilitate the exchange of oxygen for waste products, such as carbon dioxide.
- Red blood cells receive oxygen and change from purple to red.
- Red blood cells transport oxygen to all the cells in the body.
