TRANSCRIPT
AutonomicNervousSystem
Sympathetic and Parasympathetic Divisions are shown.
Sympathetic: Promotes energy expenditure, activated by emotion
and stress (e.g. increases heart rate, blood pressure)
Parasympathetic: Promotes digestion and excretion (e.g.,
stimulates salivation, stomach and intestinal activity); can be activated by severe stress
