A bronchiole refers to a part of the respiratory system in the human body that plays a crucial role in the distribution of air to the alveoli. They are smaller branches of the bronchi, and their walls are composed of smooth muscle, allowing them to regulate airflow and control the amount of oxygen reaching the lungs. The bronchioles serve as a conduit for air, facilitating efficient gas exchange and maintaining proper respiratory function.
