Where are the alveoli located?
Human BodyRespiratory System
Quick Answer
The alveoli are located at the ends of the smallest airways in the lungs. They are tiny air sacs where oxygen and carbon dioxide are exchanged.
The Full Story
Alveoli are found deep inside the lungs, clustered at the ends of bronchioles. Their thin walls and huge total surface area make gas exchange efficient, allowing oxygen to move into the blood and carbon dioxide to leave it. Humans have hundreds of millions of alveoli in both lungs combined. They are essential for breathing, and damage to them can severely affect lung function.
