Parasympathetic functions include which of the following?
A
Stimulating sweat gland secretion
B
Dilating pupils
C
Increasing blood glucose levels
D
Decreasing heart rate
Verified step by step guidance1
Understand the role of the parasympathetic nervous system: It is part of the autonomic nervous system and is responsible for 'rest and digest' functions, promoting relaxation and conserving energy.
Review the physiological effects of the parasympathetic nervous system: It decreases heart rate, stimulates digestion, constricts pupils, and promotes glandular secretions (except sweat glands, which are controlled by the sympathetic system).
Analyze the options provided: Stimulating sweat gland secretion, dilating pupils, and increasing blood glucose levels are all functions of the sympathetic nervous system, not the parasympathetic system.
Focus on the correct answer: Decreasing heart rate is a key parasympathetic function, as it helps the body relax and conserve energy during non-stressful situations.
Conclude that the correct answer aligns with the parasympathetic system's primary role in maintaining homeostasis and promoting relaxation.
