the paouch like air secs at the smallest lenchioles is called alveoli.the walls of alveoli are very thin and they are sorrounding thin blood capllaries .it is in alveoli exchange of gaseouse takes place there are so many alveoli in blood so they provides very larges surface srea for cxchanges of gaseouse
By expanding and they are million in number.
They are designed to exchange materials such as the alveoli exchange gases or the capillary walls exchange fluid and nutrients with the intestitial tissues.

In the lungs, exchange of gases occurs in the alveoli(sing: alveolus).
The actual exchange of gases occurs in the alveoli
exchange of gases in respiratory
alveoli
it is where exchange of gases takes place. :)
--it is in the alveoli where the exchange of gases occur.. :))
The alveoli are small sacs within the lungs where gas exchange occurs. They are located at the ends of bronchiole branches.
lower exchange rate,takes longer for gases to diffuse
Oxygen and carbon dioxide
The difference in the partial pressure of the gases in the blood coming to the lungs and the alveoli mediated the gas exchange. Without this difference we wont be able to breathe. Diaphragm in the thoracic cavity plays an important role in exchange of these respiratory gases.
