Hey there!
In lungs, balloon-like structures called Alveoli are present to provide maximum surface area for the Exchange of Gases.
The bronchus, within the lungs, divide into smaller tubes (bronchioles) and finally terminate in Alveoli.
The alveoli are made up of rhin moist membranes which are richly supplied with blood and provide a very large surface area for the Gaseous Exchange.
When we breathe out the air passage does not collapse because it is made from C- shaped cartilaginous rings. Which are considered to be the most powerful and strong bone structure.

HELLO DEAR,
Lungs contain millions of alveoli which provide a surface for the exchange of gases. An extensive network of blood vessels is present in the wall of the alveoli. By lifting our ribs and flatten the diaphragm, the chest cavity becomes spacious. Air is sucked into the lungs and alveoli. The oxygen from the breath, diffuses into the blood and CO2 from the blood brought from the body, diffuses out into the air.
I HOPE ITS HELP YOU DEAR,
THANKS
