The statement, that is, the sympathetic prepares the body to react, and parasympathetic helps the body to conserve and gain energy correctly describes the functions of parasympathetic and sympathetic nervous system.
What are the functions of parasympathetic and sympathetic nervous system?
Both the parasympathetic and sympathetic nervous system are the components of the autonomic nervous system. The sympathetic nervous system is situated close to the lumbar and the thoracic regions in the spinal cord.
Its main role is to instigate the body's flight or fight response. It does this by monitoring the rate of respiration and the rate of the heart. Therefore, it prepares the body to react.
On the other hand, parasympathetic nervous system is situated in between the medulla and the spinal cord, and works to stimulate the body's digest and rest and breed and feed response. Therefore, it helps the body to conserve and gain energy.
