Q

What’s the fight or flight response

A

Reflex response designed to help an individual physically under threat

22
Q

Process of fight or flight

A

Sends message to adrenal gland
Which triggers release of adrenaline to endocrine system and prompts physical changes

23
Q

What are the physical changes of the fight or flight

A 
Faster breathing rate
Muscle tension
Pupil dilation
Production of sweat
Reduced functioning of digestive system and immune system

( explain each)

24

A

group of cells specialised to secrete useful substance

25
Q

what are hormones

A

chemical messengers

26
