Answer 2

The parasympathetic nervous system does not affect the heart.

• The parasympathetic nervous system belongs to the autonomic nervous system.
• It controls the functioning of all the glands, cardiac, and smooth muscles.
• Therefore, the parasympathetic nervous system affects the pupillary smooth muscles, salivary glands, and adrenal glands.
• The main function of this nervous system is energy conservation as well as regulating the primary functions like digestion and urination.
• It is also involved in controlling the heart rate, regulating gland and intestinal activities, and relaxing the urinary tract and gastrointestinal sphincter muscles.
