Final answer:

Bronchodilation involves the relaxation of smooth muscles in the airways, leading to the widening of the respiratory passageways, making breathing easier.


Explanation:

Bronchodilation refers to the widening of the airways in the respiratory system, allowing for easier breathing. This process involves the relaxation of smooth muscles in the bronchioles, which leads to an increase in the diameter of the airway. It is controlled by the sympathetic branch of the autonomic nervous system.
