The fight-or-flight response is the way an animal responds when stressed.
What does the body do?
The body becomes physiologically aroused in readiness to fight an aggressor or, in some cases, flee
Adrenaline

Adrenaline is a hormone produced by the adrenal glands that is part of the human body’s immediate stress response system.
What does adrenaline have a strong effect on?
Adrenaline has a strong effect on the cells of the cardiovascular system
Adrenaline is a hormone produced by the adrenal glands that is part of the human body’s immediate stress response system.
Adrenaline has a strong effect on the cells of the cardiovascular system - doing what?
Adrenaline has a strong effect on the cells of the cardiovascular system - Stimulating the heart rate, contracting blood vessels and dilating air passages
Hypothalamus
The hypothalamus is a part of the brain that is located in the centre of the brain and deals with basic survival functions
Adrenal gland
The adrenal gland is the gland in the adrenal system that releases adrenaline
Adrenal medulla
The adrenal medulla is the central part of the adrenal gland
What is the fight-or-flight response generated from?
The fight-or-flight response is generated from the autonomic nervous system
The fight-or-flight response is generated from the autonomic nervous system, specifically what?
The fight-or-flight response is generated from the autonomic nervous system, specifically the sympathetic branch
The fight-or-flight response is generated from the autonomic nervous system, specifically the sympathetic branch.
It is a what response?
It is a reflex response
The fight-or-flight response is generated from the autonomic nervous system, specifically the sympathetic branch.
It is a reflex response designed to help an individual do what when under threat?
It is a reflex response designed to help an individual manage physically when under threat
The fight-or-flight response is generated from the autonomic nervous system, specifically the sympathetic branch.
It is a reflex response designed to help an individual manage physically when under threat.
When it is also activated?
It is also activated in times of stress
The fight-or-flight response is generated from the autonomic nervous system, specifically the sympathetic branch.
It is a reflex response designed to help an individual manage physically when under threat.
It is also activated in times of stress, why?
It is also activated in times of stress, because the body perceives stress to be a threat
The fight-or-flight response is generated from the autonomic nervous system, specifically the sympathetic branch.
It is a reflex response designed to help an individual manage physically when under threat.
It is also activated in times of stress, because the body perceives stress to be a threat.
The fight-or-flight response helps an individual to react how than normal?
The fight-or-flight response helps an individual to react quicker than normal
The fight-or-flight response is generated from the autonomic nervous system, specifically the sympathetic branch.
It is a reflex response designed to help an individual manage physically when under threat.
It is also activated in times of stress, because the body perceives stress to be a threat.
The fight-or-flight response helps an individual to react quicker than normal and facilitates what functioning?
The fight-or-flight response helps an individual to react quicker than normal and facilitates optimal functioning
The fight-or-flight response is generated from the autonomic nervous system, specifically the sympathetic branch.
It is a reflex response designed to help an individual manage physically when under threat.
It is also activated in times of stress, because the body perceives stress to be a threat.
The fight-or-flight response helps an individual to react quicker than normal and facilitates optimal functioning, so that they can what?
The fight-or-flight response helps an individual to react quicker than normal and facilitates optimal functioning, so that they can:
1. Fight the threat
Or,
2. Run away from it
The fight-or-flight response is generated from the autonomic nervous system, specifically the sympathetic branch.
It is a reflex response designed to help an individual manage physically when under threat.
It is also activated in times of stress, because the body perceives stress to be a threat.
The fight-or-flight response helps an individual to react quicker than normal and facilitates optimal functioning, so that they can fight the threat or run away from it.
This occurs in a series of steps:
1. What does the hypothalamus recognise?
The hypothalamus recognises that there is a threat
