Trachea connects the throat to the lungs, like a passage.

This is where the gas exchange happen. 
The capillary network surrounding the alveoli, it helps the gas exchange.
The oxygen that breathe in will pass the alveolus into the capillary networks, and through the blood circulation, transfer to the body tissues, to supply the energy of body organs.
