What are these air sacs called?
alveoli
Inhaled air passes through tiny ducts from the bronchioles into elastic air sacs (alveoli).
What are the air sacs in birds?
Air sacs serve as internal compartments which hold air and facilitate internal air passage to allow birds to have a continuous flow of large volumes of air through the lungs as a way to increase oxygen exchange capacity and efficiency.
What is the grape like clusters of air sacs within lungs?
alveoli Grapelike clusters of round sacs in the lungs; site of gas exchange. bronchioles Smaller air tubes in the lungs that are as thin as a strand of hair and end in tiny air sacs called alveoli.
What are thin-walled air sacs at the end of bronchioles?
Tiny air sacs at the end of the bronchioles (tiny branches of air tubes in the lungs). The alveoli are where the lungs and the blood exchange oxygen and carbon dioxide during the process of breathing in and breathing out.
What do you call the cluster of air sacs in lungs?
When you breathe, air travels to your lungs through airways called bronchi. The bronchi divide into smaller airways, called bronchioles, which end in clusters of tiny air sacs, called alveoli.
What happens if the air sacs are damaged?
In emphysema, the inner walls of the lungs’ air sacs (alveoli) are damaged, causing them to eventually rupture. This creates one larger air space instead of many small ones and reduces the surface area available for gas exchange. Emphysema is a lung condition that causes shortness of breath.

What is air sacs in lungs?
Alveoli are tiny air sacs in your lungs that take up the oxygen you breathe in and keep your body going. Although they’re microscopic, alveoli are the workhorses of your respiratory system. You have about 480 million alveoli, located at the end of bronchial tubes.
