The fallow is briefly mention the sympathetic and parasympathetic activation on the impact of. (Note that these effects usually are mutually antagonistic.)

CNS
Structure	Stimulate sympathetic	sti-parasympathetic
Examples	This is the "fight" or "flight" response. Is a sunny days, you comfortable to walking in the park. Suddenly an angry bear appears on the front. You will be poised to go, or turn away? Now, your sympathetic activation- increased blood pressure, heart rate, digestion slows down, so to meet the energy consumption.,	Such the sunny day,however you leisurely walk in the park .you decide to bring their own chairs to sit on relax. this is call"rest and digest" response.so know -blood pressure ,heart rate slow down ,start the digestion -and to save energy.
Iris Salivary gland	Pupil dilated   decreased saliva	Pupil to narrow Increased saliva
Mouth / nasal	Mucus reduce	Mucus increased
Hart rate	fase	slower
Lung	bronchial muscle relaxation	bronchial muscle contraction
stomach	reduced motility	secretion of gastric ; motility increased.
small intestine	reduced motility	Increase in digestion
large intestine	Reduced	increased(secretion & motility)
Liver	Stimulated hepatic glucose into glucose
Kidney	urine excretion reduce	urine excretion increas
Adrenal gland	Norepinephrine and epinephrine secretion
Bladder	the wall relaxation and urethral sphincter	Wall contraction Urethral sphincter relaxation
