  4. <em><u>Bronchi:</u></em> The trachea divides into two primary bronchi; they are the main passageway into the lungs.
  5. <em><u>Bronchioles: </u></em>The bronchi develop smaller the closer they get to the lung tissue and are then consider bronchioles.
  6. <em><u>Alveoli:</u></em> They are tiny air sacs located at the end of the bronchioles, which is the site of oxygen and carbon dioxide exchange in the respiratory system.
