The purpose of the sympathetic nervous system in the human body is to activate the "fight or flight" response in times of stress or danger. This system helps prepare the body for action by increasing heart rate, dilating airways, and redirecting blood flow to muscles.
The sympathetic nervous system is responsible for the body's "fight or flight" response, which helps prepare the body to react to stressful situations by increasing heart rate, dilating airways, and releasing adrenaline.
You could say there are 2, The Central Nervous System(CNS), & the Peripheral Nervous System (PNS).To be more inclusive, here is a list of human nervous systems:The Central Nervous System (CNS), the Peripheral Nervous System (PNS),the Somatic Nervous System (SNS), the Autonomic Nervous System, the Sympathetic Nervous System, and the Parasympathetic Nervous System.That would make a total of 6, although the Sympathetic and Parasympathetic are parts of the Autonomic Nervous system, which could mean a total of 4, and the Autonomic is itself a part of the Peripheral Nervous System, which would bring the total back to 2.The Central Nervous System is comprised of the brain and the spinal cord;the Peripheral Nervous System connects the CNS to other parts of the body, and is comprised of the Somatic Nervous System and the Autonomic Nervous System;the Somatic Nervous System includes all the nerves controlling the body's muscular system, and sensory nerves;the Autonomic Nervous System consists of motor neurons which control internal organs, and is comprised of two sub-systems, the Sympathetic Nervous System, and the Parasympathetic Nervous System;the Sympathetic Nervous System is involved in the fight-or-flight response, and the Parasympathetic Nervous System is involved in relaxation.
The two divisions of the human nervous system are the central nervous system (CNS), which includes the brain and spinal cord, and the peripheral nervous system (PNS), which consists of all the nerves outside the CNS that connect it to the rest of the body.
Partly the Cranial nerve and partly the spinal chord. also known as the peripheral nervous system
The human nervous system does not play a direct role in removing wastes from the body. Waste removal is primarily carried out by the urinary system, respiratory system, digestive system, and integumentary system.
The two major divisions of the human nervous system are the central nerves and the peripheral nerves.
The sympathetic nervous system is responsible for the body's "fight or flight" response, which helps prepare the body to react to stressful situations by increasing heart rate, dilating airways, and releasing adrenaline.

A human nervous system is much more complex. Unlike a human a jellyfish does not have a central nervous system.

The human brain belongs to the nervous system.
Autonomic nervous system is that part of the nervous system that controls the body function that are not consciously controlled by the human brain like breathing, heartbeat, and digestive processes. Autonomic nervous system is a part of the peripheral nervous system. It works along with the somatic nervous system to regulate the body functions.
The nervous system.
You are probably referring to "involuntary body functions" - and the answer would be the autonomic nervous system. This system could be further divided into the sympathetic nervous system and the parasympathetic nervous system.
In short, stimulation of the sympathetic branch of the autonomic nervous system prepares the body for emergencies: for "fight or flight". This system allows for these reactions to occur with out upsetting the balance of the human body. It increases activity that is necessary to the "fight or flight" response(ex: blood pressure, heart rate, and adrenaline) and decreases activity that is unnecessary (ex: salivation and digestion)
The human nervous system is centralized at the brain.
The peripheral nervous system.
