 Spiracles
-------------------------------------------
they are the small holes present in insects etc on their exoskeleton which helps them in respiration , it helps them to transport of oxygen directly to the trachea and it also performs gas exchange
----------------------------------------------------------------------------------------------------
Bronchi
------------------------------------------------
It is the passage through which air passes into the lungs in the respiratory tract , then bronchi gents into the lungs , it is called as bronchioles in it and then they get evolved into air sacs where the exchange of gases takes place
