Bronchioles
Bronchioles are small airways in the lungs that branch off from the bronchi. They are responsible for carrying oxygen-rich air to the alveoli, which are tiny air sacs where gas exchange occurs.
Path of Oxygen
- When we breathe in, air enters the respiratory system through the trachea.
- The trachea branches into two bronchi, one leading to each lung.
- The bronchi further divide into smaller tubes called bronchioles.
- Oxygen in the bronchioles ultimately reaches the alveoli, where it diffuses into the bloodstream and carbon dioxide is removed.
Gas Exchange
- In the alveoli, oxygen from the air we breathe crosses the thin walls of the air sacs and enters the bloodstream.
- At the same time, carbon dioxide, a waste product of metabolism, moves from the blood into the alveoli to be exhaled.
Importance of Bronchioles
- Bronchioles play a crucial role in ensuring that oxygen reaches the alveoli for efficient gas exchange.
- Their small size and branching structure help in distributing air evenly throughout the lungs.
- Any blockages or restrictions in the bronchioles can impair the flow of air and impact the exchange of gases in the lungs.
