dilates bronchioles

produces \goosebumps\

increases heart rate and force of contraction

contracts smooth muscle of the bladder wall and relaxes urethral sphincter

Explanation:

1. Analyze each option:

• Dilating bronchioles, producing "goosebumps", and increasing heart rate/force of contraction are functions of the sympathetic division (fight - or - flight response).
• The parasympathetic division (rest - and - digest) is responsible for functions like contracting the smooth muscle of the bladder wall to help in urination (and relaxing the urethral sphincter to allow urine to pass).

Answer:

D. contracts smooth muscle of the bladder wall and relaxes urethral sphincter
