Which symptom result from the parasympathetic branch of the autonomic nervous system?
You might find your answer here, although you may be asking about a symptom when something is wrong with the parasympathetic branch of the autonomic nervous system.

I deleted your two posts requesting answers to an exam.
Why would you pay money for a class and then cheat?

The parasympathetic branch of the autonomic nervous system is responsible for controlling many of the body's rest-and-digest functions. It works in opposition to the sympathetic branch, which is responsible for the fight-or-flight response. When the parasympathetic branch is activated, it produces several distinct symptoms, including:
1. Slowing of heart rate: The parasympathetic nervous system released acetylcholine, which acts on the heart's pacemaker cells to slow down the heart rate.
2. Constriction of pupils: Activation of the parasympathetic nervous system causes the circular muscles in the iris to contract, resulting in the constriction of the pupils (miosis).
3. Increased salivation: Parasympathetic stimulation leads to increased production of saliva, which aids in digestion.
4. Increased gastrointestinal activity: The parasympathetic branch promotes digestion by increasing gastrointestinal motility, stimulating the secretion of digestive enzymes, and increasing blood flow to the digestive organs.
5. Bronchoconstriction: Activation of the parasympathetic branch causes the smooth muscles surrounding the bronchioles to contract, resulting in narrowed airways and increased resistance to airflow.
These symptoms are characteristic of the parasympathetic branch and can be remembered using the acronym SLUDD: Salivation, Lacrimation (tearing), Urination, Digestion, and Defecation.
