4. Fight-or-Flight Parasympathetic NS Sympathetic NS Pupils & Tears Salivation Heart Rate Respiration and Blood Vessels Digestion Bladder Elimination Genitals Constricts pupils Stimulates tears Stimulates salivation Heart rate & blood pressure decreases Decreases respiration Constricts bronchi & blood vessels Stimulates digestion Contracts bladder Stimulates elimination Inhibits genitals Dilates pupils Inhibits tears Inhibits salivation Dry mouth Increases heart rate Blood pressure increases Blood vessels dilate Increases respiration Bronchi dilate Oxygen levels increase Inhibits digestion Adrenaline Release of adrenaline (located on top of kidneys) Sugar Releases sugar/glucose from the liver (extra energy for muscles) Relaxes bladder (temporary loss of bladder control) Inhibits elimination Excites genitals
