Hey...Dear friend •○•

Good Question though!!
---------------------------------
Your ans.
When we breathe in, we inhale Oxygen. These Oxygen goes from the nostrils Via pharynx to Bronchi. Within the Lungs, the passage divides into smaller and smaller tubes known as alveoli.
These alveoli are the site of gaseous exchange.The walls of an alveoli contains an extensive network of blood vessels.Because of this. when we breathe in air is sucked into the lungs and fills the expanded alveoli.The blood on the way, brings C02 from the rest of the body for futher release into alveoli and the oxygen in the alveolar ait is taken up by blood in the alveolar blood vessels to be transported to all the cells of the body.
I hope u had found this ans. pragmatic..☺
