Called Takes Tubes Bronchioles State Pathway Air Breath

The pathway of inhaled air starts from the mouth, goes through the trachea, which branches into bronchi, then bronchioles, finally reaching the alveoli where gas exchange occurs.

La voie de l'air que vous respirez commence dans la bouche et passe par la trachée, qui se divise en bronches, puis en bronchioles, pour finalement atteindre les alvéoles où l'échange gazeux se produit.

Front State the pathway that the air you breath in takes from the mouth to the alveoli.
Back
  1. It goes through the trachea
  2. This spluts into two tubes called "bronchi", one going to each lung
  3. The bronchi split into progressively smaller tubes called bronchioles
  4. The bronchioles finally end at small bags called alveoli where the gas exchange takes place by diffusion.
