Adrenaline is released from the adrenal gland and causes the ‘fight’ or ‘flight’ response to dangerous stimul. The adrenal gland stops releasing adrenaline when the danger is over so the body can return to rest.
What are the effects of adrenaline?
Heart and breathing rate increases
Stored glycogen in the liver is converted to glucose for respiration
Pupils dilate to let in more light
Mental awareness increases
Blood is diverted away from your digestive system to the muscles of the limbs
