How will you describe the pathway of oxygen in the breating system


The air we breathe goes through the nose, nasal passages, and then through our trachea or also known as windpipe, which is separated into two branches called the bronchi or bronchial tubes. The bronchi subdivide many times inside our lungs, analogous to the branching pattern of grapes, finally becoming hairlike tubes called the bronchioles. In the last part of the terminal bronchioles are tiny bubble-like bunch of structures called alveoli or known as airsacs
Straight to our lungs
Nose goes to nasal cavity,trachea,bronchi,bronchioles then goes into the alveoli
You inhale air into your nose or mouth, and to nassal passages for filtering and warming of the air. And it travels down into your windpipe, or trachea then to the bronchia tubes pass through the lungs which divided into smaller air passages called bronchioles. The bronchioles end in tiny balloon-like air sacs called alveoli. :)

Do you know the answer?
