The sympathetic nervous system is responsible for the 'fight or flight' response, which prepares the body to react in stressful or emergency situations. When activated, this part of the autonomic nervous system induces several physiological changes: it increases heart rate, dilates airways, and redirects blood flow away from digestive organs toward muscles, enhancing physical performance and alertness. This response is crucial for survival as it allows individuals to either confront or escape from threatening situations.

In contrast, the parasympathetic nervous system facilitates a 'rest and digest' state, promoting relaxation and recovery. The central nervous system, comprising the brain and spinal cord, does play a role in processing information and coordinating responses but does not directly regulate the bodily changes associated with the 'fight or flight' mechanism. Additionally, the somatic nervous system controls voluntary movements and sensory information but is not involved in automatic responses to stress.
