Answer 1

Paolo is enjoying his fishing vacation to Alaska when he surprises a napping bear. Paolo is running from the angry bear.

The sympathetic pathway of his peripheral nervous system effects:-

Heart rate - His heart rate and cardiac output will increase to provide more blood to muscle in this flight situation.

Blood vessels - the sympathetic pathways of his peripheral nervous system constrict the blood vessel to raise blood pressure and to provide more blood to the targeted are like leg muscles and brain.

Bronchioles - In this case, his bronchiole will widen, which allows more air to get into the lungs. It improves oxygenation which will improve muscle activity.

Urinary bladder - Increase the storage of urine.

Sweat glands - Increases activity of sweet gland(Increase sweating)

Digestive motility - Inhibit digestive motility.
