The walls of the bronchi contain muscles that can cause the airway to expand (widen) or contract (narrow). For example, during , the airway expands to increase airflow (ventilation). Conversely, when exposed to polluted or very air, the airway contracts to protect the downstream tissues from injury. The smaller branches of the bronchial tree, called , also contain muscle, but they lack cartilage. Notice in Figure 1 that the very smallest bronchioles (respiratory bronchioles) connect directly to tiny air sacs in the lung, called alveoli. Figure 2 shows a microscopic section of a normal bronchial wall.
