Verified step by step guidance

Understand the role of the sympathetic nervous system (SNS): The SNS is part of the autonomic nervous system responsible for the 'fight or flight' response, preparing the body for stressful or emergency situations.
Identify the typical effects of the sympathetic nervous system: Common effects include increased heart rate, dilation of pupils, and relaxation of airways to enhance oxygen intake and prepare the body for action.
Consider the effect on digestive activity: The SNS typically inhibits digestive activity because digestion is not a priority during a 'fight or flight' response. Instead, energy is redirected to more immediate survival functions.
Compare the options given: Analyze each option to determine if it aligns with the typical 'fight or flight' responses of the SNS.
Determine which option does not fit: Since stimulation of digestive activity is not consistent with the SNS's role in inhibiting digestion during stress, it is the effect that does not belong to the sympathetic nervous system's actions.
