Step 1
B Nose, trachea, bronchi, bronchioles, alveoli

The correct pathway for air through the respiratory system starts at the nose, where air is inhaled. It then moves to the trachea, which serves as the main airway. From there, the air travels into the bronchi, which branch off into the bronchioles, and finally reaches the alveoli, where gas exchange occurs.
