Verified step by step guidance

Understand the role of the sympathetic nervous system (SNS) in the body. The SNS is part of the autonomic nervous system responsible for the 'fight or flight' response, which prepares the body to respond to stress or danger.

Recognize that during sympathetic activation, the body prioritizes functions that are essential for immediate survival, such as increasing heart rate, dilating airways, and redirecting blood flow to muscles.

Identify which systems are enhanced and which are suppressed during this response. The cardiovascular and respiratory systems are typically enhanced to support increased physical activity.

Consider the digestive system's role in the body. It is responsible for processing food and absorbing nutrients, which is not immediately necessary during a 'fight or flight' situation.

Conclude that the digestive system is suppressed during sympathetic nervous system activation, as energy and resources are diverted away from digestion to support more critical functions for immediate survival.
