The bronchi transport gases between the environment and the lung parenchyma. The bronchial tree also protects alveoli from small particulate matter in the inhaled air. The bronchi are lined with goblet cells that secrete mucus and entrap the particles. The bronchi are lined with cilia which sweep particles upward where they can be swallowed or expelled. The right mainstem bronchus is wider, shorter, and more vertical than the left; therefore, it is prone to aspiration pneumonia.
