Activation of the sympathetic branch of the autonomic nervous system results in which of the following responses?
A
Decreased respiratory rate and constricted pupils
B
Enhanced digestive activity and increased saliva production
C
Lowered blood pressure and slowed heart rate
D
Increased heart rate and pupil dilation
Verified step by step guidance1
Step 1: Understand the role of the sympathetic branch of the autonomic nervous system. It is part of the 'fight or flight' response, which prepares the body to respond to stress or danger.
Step 2: Identify the physiological changes associated with the sympathetic response. These include increased heart rate, pupil dilation, decreased digestive activity, and reduced saliva production.
Step 3: Compare the options provided in the problem with the known effects of sympathetic activation. Eliminate choices that contradict the 'fight or flight' response, such as decreased respiratory rate or enhanced digestive activity.
Step 4: Focus on the correct physiological responses: increased heart rate and pupil dilation. These changes help the body respond to stress by improving oxygen delivery and visual acuity.
Step 5: Confirm that the correct answer aligns with the physiological effects of sympathetic activation: 'Increased heart rate and pupil dilation.'
