Quizplus · Accepted Answer

Parasympathetic functions are responsible for the relaxation response in the body. This includes the activation of the pupillary constrictor muscles causing the lens to accommodate for close vision. Option B is incorrect as the parasympathetic nervous system slows heart rate and reduces the force of contraction. Option C is incorrect as it is the opposite of what the parasympathetic nervous system does, which is to lower blood glucose levels. Option D involves the sympathetic nervous system, not the parasympathetic nervous system.
