Biopsych -> Fight or flight response

Question 1

Direct Effects of Adrenaline;

Answer 1

Increased heart rate,
Constricted blood vessels (increasing rate of blood flow and raising blood pressure),
Blood diverted away from the skin, kidneys and digestive system,
Increased respiration,
Increased sweating,
Pupil dilation,
Saliva production stopped (can cause dry mouth)
Digestion is inhibited (can cause butterflies in stomach or nausea)
Glucose released, increasing blood sugar levels (fuel for muscles).

Question 2

General Effects of Adrenaline

Answer 2

The general effects of adrenaline are to prepare the body for physical action by increasing blood supply/oxygen to skeletal muscles and prepare for rapid response planning by increasing the oxygen supply to the brain.

Question 3

The Parasympathetic Nervous System (PNS)

Answer 3

When the threat has passed the PNS dampens down the stress response. Adrenaline levels return to normal which returns heart/breathing rate to normal. Digestion, which is stopped when the SNS is active, restarts.
