  7. Bronchioles • Branches of bronchus • Delivers air to the Lungs

  8. Bronchioles • Branches of bronchioles • Delivers air to the Lungs

  9. Lungs • Main organs of the respiratory system. • Oxygen is taken into the body and carbon dioxide is breathed out. • The RBC are responsible for picking up the oxygen it to all the body cells that need it and remove carbon dioxide.
