The sympathetic nervous system is responsible for responses such as pupil dilation, increased heart rate, and increased respiration.

The sympathetic nervous system is part of the autonomic nervous system, which controls involuntary bodily functions. It is activated in times of stress or emergency, often referred to as the “fight-or-flight” response. When the sympathetic nervous system is activated, it prepares the body for action, increasing alertness and physical readiness.

One of the key effects of sympathetic activation is the dilation of the pupils. This allows more light to enter the eyes, improving vision and alertness. Another effect is an increase in heart rate, which helps to deliver oxygen and energy-rich blood to the muscles more efficiently. Additionally, sympathetic activation leads to increased respiration, allowing for a higher oxygen intake and improved oxygen exchange in the lungs.

Overall, the sympathetic nervous system plays a crucial role in preparing the body for immediate action in response to perceived threats or stressful situations.
