Which of the following are likely to occur during the fight-or-flight response?
Respiration increases, blood pressure rises, pupils dilate
.
What happens to the body during the fight-or-flight response quizlet?
Responses include
an increase in heart rate, blood pressure and cardiac output
, increased pupil size and metabolic changes such as fat and glycogen into the blood stream.
Which of the following are likely to occur during the fight-or-flight response?
The fight-or-flight response is characterized by an
increased heart rate (tachycardia)
, anxiety, increased perspiration, tremour, and increased blood glucose concentrations (due to glycogenolysis, or breakdown of liver glycogen).
Where does the fight-or-flight response occurs?
During a fight-flight-freeze response, many physiological changes occur. The reaction begins
in your amygdala
, the part of your brain responsible for perceived fear. The amygdala responds by sending signals to the hypothalamus, which stimulates the autonomic nervous system (ANS).
What happens when your body is in constant fight or flight mode?
But when
stressors are always present and you constantly feel
under attack, that fight-or-flight reaction stays turned on. The long-term activation of the stress response system and the overexposure to cortisol and other stress hormones that follows can disrupt almost all your body’s processes.
What is the fight-or-flight response quizlet?
Define the fight or flight response.
A physiological reaction that occurs in response to a perceived harmful event, attack, or threat to survival
.
Which hormones control the fight-or-flight response?
Adrenaline
is a hormone released from the adrenal glands and its major action, together with noradrenaline, is to prepare the body for ‘fight or flight’.
What are the 3 stages of fight or flight?
There are three stages:
alarm, resistance, and exhaustion
. Alarm – This occurs when we first perceive something as stressful, and then the body initiates the fight-or-flight response (as discussed earlier).
What part of the brain initiates the fight-or-flight response?
To produce the fight-or-flight response,
the hypothalamus
activates two systems: the sympathetic nervous system and the adrenal-cortical system. The sympathetic nervous system uses nerve pathways to initiate reactions in the body, and the adrenal-cortical system uses the bloodstream.
What body processes slow down during the fight-or-flight response?
First, the fight-or-flight response is not at all dangerous—it is meant to help you, not harm you. Second,
the parasympathetic nervous system
is an inbuilt protector which slows down the sympathetic nervous system after a while. Another important point is that adrenalin takes time to fully exit the blood stream.

- Sweating: Running or wrestling with bears will certainly cause an increase in body heat.
What triggers fight or flight?
The autonomic nervous system has two components, the
sympathetic nervous system
and the parasympathetic nervous system. The sympathetic nervous system functions like a gas pedal in a car. It triggers the fight-or-flight response, providing the body with a burst of energy so that it can respond to perceived dangers.
Can you get stuck in fight or flight mode?
People with higher pain levels often experience heightened fight-or-
flight
responses, which throws the nervous system off-balance. Things like stress, pain, and lack of sleep trigger these responses. When we’re stuck in fight-or-flight mode, our automatic functions stop working properly.
Does anxiety cause high cortisol?
As a result, emotional states such as
anxiety might produce more substantial elevation in cortisol in older adults
