A
Increased blood pressure
B
Bronchodilation
C
Decreased heart rate
D
Pupil dilation
Verified step by step guidance1
Understand that the autonomic nervous system has two main branches: the sympathetic and parasympathetic nervous systems, which generally have opposite effects on the body.
Recall that the parasympathetic nervous system is often called the 'rest and digest' system because it promotes calming and maintenance functions in the body.
Identify the typical responses of the parasympathetic nervous system, such as slowing the heart rate, constricting pupils, and promoting digestion.
Compare each option with the known effects of the parasympathetic nervous system: increased blood pressure and bronchodilation are sympathetic responses, pupil dilation is also sympathetic, while decreased heart rate aligns with parasympathetic activity.
Conclude that the correct response of the parasympathetic nervous system from the given options is decreased heart rate.
