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?
