The parasympathetic nervous system serves as the "rest and digest" system, which results in vasodilation of the peripheral vessels. This results in an overall decrease in blood pressure :)

Heart muscles has there own rhythm of contraction. The sinoatrial node has the fastest rate of contraction. That is why it governs the rhythm of the heart. You have the control of the autonomic nervous system over the heart rate. Stimulation of the sympathetic nervous system increase the heart rate. Stimulation of the parasympathetic nervous system decrease the heart rate.

Sympathetic and parasympathetic nervous system's are subdivisions of what nervous system?
The sympathetic and parasympathetic nervous systems are subdivisions of the autonomic nervous system.
Does the parasympathetic nervous system increase or decrease heart rate?
Both the parasympathetic and sympathetic nervous systems innervate the heart. The parasympathetic nervous system functions in regulating heart rate through the vagus nerve, with increased vagal activity producing a slowing of heart reate. The sympathetic nervous system has an excitatory influence on heart rate and contractlitiy, and it serves as the final common pathway for controlling the smooth muscle tone of the blood vessels.

What does the parasympathetic nervous system stimulate in the micturition reflex?
The parasympathetic nervous system allows the act of micturition. The sympathetic nervous system inhibits it.
What part of the autonomic nervous system causes an increase in digestive tract mobility?
Stimulation of the Parasympathetic nervous system causes an increase in digestive tract mobility. When stimulated the parasympathetic post-ganglionic neurons release a hormone called Acetylcholine. This causes the Digestive tract to increase its contractions. Counteracting this increase in digestive tract mobility is the sympathetic nervous system, which releases a hormone called noradrenaline which slows down the digestive tracts contractions. This is how the Parasympathetic Nervous System gets the name "rest and digest"
