When you are excited your pupils dilate, heart speeds up, you perspire, etc. Sympathetic Nervous System Active in emotional or excited states. Works as a unit.

11. The Nervous System Peripheral Nervous System Autonomic “Automatic” Nervous System Parasympathetic Nervous System Active in relaxed states. Stimulates one organ at a time. Ex: slows heart rate. ¡Para!=Stop/Slow down Parasympathetic Nervous System Active in relaxed states. Stimulates one organ at a time. Ex: slows heart rate. ¡Para!=Stop/Slow down

12. Please explain which part of the autonomic nervous system (either parasympathetic or sympathetic) is at work in the following scene: Over the past several months you have applied to several colleges. As you approached the mailbox yesterday you saw a letter from DePaul University. (Your top choice for school.) Your heart started to race, your palms began to sweat, and your pupils dilated. Finally, you managed to get the letter open. You were accepted! Eventually your heart rate decreased and your pupils returned to their normal state and you quit sweating.
