in the lungs
BRonchi True
The Trachea comes down and splits into the 2 Bronchi at the Bifurcation of trachea, at the lowest point in the spit it is called the "carina". The two Bronchi are called the left and right primary bromchi, and then they quickly spit again into secondary bronchi. Hope that helps
Air moves from the larynx into the bronchial tubes then enters the lungs and is filtered into oxygen and other components by the avioli. The oxygen goes to the blood, and the other molecules (nitrogen, argon,helium,hydrogen etc.) are breathed out.
