Sympathetic stimulation of the lungs produces which combination of effects?

Explanation:
Sympathetic activation in the lungs relaxes airway smooth muscle and constricts pulmonary vessels. Norepinephrine released from sympathetic nerves binds to beta-2 adrenergic receptors in bronchial smooth muscle, causing bronchodilation and increased airway diameter. At the same time, it acts on alpha-adrenergic receptors in the pulmonary arteries, producing vasoconstriction. The result is bronchodilation with vasoconstriction of the lung vessels, aligning airflow with perfusion during a fight-or-flight state.
