During an emergency, the sympathetic nervous system releases hormones such as adrenaline (epinephrine) and norepinephrine. These hormones prepare the body for a "fight or flight" response by increasing heart rate, dilating airways, and boosting energy availability. This physiological response enhances alertness and physical performance, allowing the body to react quickly to threats.
