What will happen to our internal organs when we are under parasympathetic or sympathetic?

When the sympathetic nervous system is activated, often referred to as the "fight or flight" response, internal organs experience increased heart rate, dilated airways, and redirected blood flow away from the digestive system, preparing the body for quick action. In contrast, activation of the parasympathetic nervous system, known as the "rest and digest" response, promotes a decrease in heart rate, enhanced digestion, and increased blood flow to the gastrointestinal tract, facilitating recovery and energy conservation. These opposing responses help maintain homeostasis and adapt the body to various stressors and relaxation needs.
