  4. segmental (tertiary) bronchus
  5. Bronchioles
• Function of Trachea?

  • delievers air through mediastinum to main bronchi
• Function of main (primary) bronchus?

  • branch from trachea to deliver air to each lung
• Function of lobar (secondary) bronchus?

  • branch from main bronchi that delivers air to each lobe
• Function of segmental (tertiary) bronchus?

  • branch from lobar bronchi to deliver air to each bronchopulmonary segment
• Function of bronchioles?

  • branch from segmental bronchi to deliver air to respiratory zone inside a bronchopulmonary segment
• Respiratory Zone
