Heya Dear !!
_________
Here Is Your Ans.---------->
Lungs contain millions of alveoli which provide a surface for the exchange of gases. An extensive networkof 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 CO2from the blood brought from the body, diffuses out into the air.
Hope It Helps You ☺
