Question

Quizplus · Accepted Answer

Activation of the beta₂-adrenergic receptors of the airway causes bronchodilation, which expands the airways and increases air flow. This is why beta₂-adrenergic agonists such as albuterol are used to treat asthma and other respiratory conditions. Activation of these receptors would not cause laryngospasm, constrict the bronchioles, or restrict air flow.
