PHYSICAL INDICATION OF FIGHT OR FLIGHT RESPONSE - Teachoo.jpg

Adrenaline is released by the adrenal glands into the blood when the body is in a stressful situation .

The following processes are carried out once adrenaline is released.

  • Heart beats faster , resulting in supply of more oxygen to our muscles
  • Blood to the digestive system and skin is reduced due to contraction of muscles around small arteries in these organs
  • This diverts blood to our skeletal muscles
  • The breathing rate increases because of the contractions of the diaphragm and the rib muscles.

All of this leads to fight or flight response.
