Alveolar ventilation would be expected to increase in response to which of the following events? A. Activation of the parasympathetic nervous system B. Activation of the sympathetic nervous system C. Secretion of acetylcholine D. Secretion of serotonin E. Both a) and c) are correct
Homework Answers
Answer
B) Activation of sympathetic nervous system
Explanation :- Activation of sympathetic nervous system causes stimulation of beta 2 Adrenergic receptors of the airways causing the bronchidilation that increases the air flow and increase alveolar ventilation
