Bronchioles are numerous because they play a crucial role in efficiently distributing air throughout the lungs. Their extensive branching increases the total surface area for gas exchange, allowing for more effective oxygen and carbon dioxide transfer. This intricate network also helps regulate airflow and resistance within the respiratory system, ensuring that air reaches the alveoli, where gas exchange occurs. The high number of bronchioles enhances the overall respiratory capacity of the lungs.
