Understand the role of the parasympathetic nervous system: It is part of the autonomic nervous system responsible for 'rest and digest' functions, promoting relaxation and recovery.
Identify the effects typically associated with the parasympathetic nervous system: These include decreased heart rate, increased digestive activity, and constriction of pupils.
Analyze each option: 'Decreased heart rate' aligns with the parasympathetic function of promoting relaxation and conserving energy.
Consider the other options: 'Increased heart rate' and 'Dilation of pupils' are typically associated with the sympathetic nervous system, which prepares the body for 'fight or flight' responses.
Conclude that 'Decreased heart rate' is the correct effect of the parasympathetic nervous system, as it aligns with its role in reducing energy expenditure and promoting rest.
