What are the results of activation of the sympathetic nervous system (SNS)?
Understand the Problem
The question is presenting information about the activation of the sympathetic nervous system (SNS) and its physiological effects, such as increased blood pressure and heart rate, respiratory efficiency, bronchi dilation, pupil dilation, and blood diversion from the gastrointestinal tract and internal organs.
Answer
Increased heart rate, blood pressure, respiratory efficiency; diverted blood from GI tract.
Activation of the sympathetic nervous system results in increased blood pressure and heart rate, enhanced respiratory efficiency, bronchial dilation, pupil dilation, and diversion of blood away from the gastrointestinal tract and internal organs.
Answer for screen readers
Activation of the sympathetic nervous system results in increased blood pressure and heart rate, enhanced respiratory efficiency, bronchial dilation, pupil dilation, and diversion of blood away from the gastrointestinal tract and internal organs.
More Information
The sympathetic nervous system prepares the body for stressful situations, also known as the 'fight or flight' response. This response helps the body manage situations perceived as threats.
Tips
A common mistake is neglecting the holistic impact of SNS activation; it affects multiple systems simultaneously, not just one.
