The sympathetic nervous system (SNS) is a component of the autonomic nervous system that prepares the body for "fight or flight" responses during stressful situations. It increases heart rate, dilates airways, and redirects blood flow to essential muscles, enhancing physical performance and alertness. The SNS also stimulates the release of adrenaline and other hormones, facilitating rapid physiological changes to cope with perceived threats. Overall, it plays a crucial role in managing the body's response to stress and emergencies.
