What dilates in the fight- or-flight response?
During the fight-or-flight response, several physiological changes occur, including the dilation of the pupils and bronchioles in the lungs. This dilation enhances vision and increases airflow, allowing for improved oxygen intake to support heightened physical activity. Additionally, blood vessels in the muscles may dilate to increase blood flow, providing the necessary energy for a quick response to threats.
What happens to the lungs during the fight or flight response?
During the fight or flight response, the sympathetic nervous system activates to increase breathing rate and expand the airways in the lungs. This allows more oxygen to be taken in and circulated throughout the body to prepare for the physical demands of the stressful situation.
Why during fight or flight do your muscles become tense?
During the fight or flight response, the body releases stress hormones like adrenaline, which increase muscle tension to prepare for a physical response. This increased muscle tension helps to improve strength and speed in either fighting or fleeing from a threat.
What are three phiscial changes that occur during the Alarm Stage?
During the Alarm Stage of the body's stress response, several physical changes occur. The body releases adrenaline and cortisol, leading to increased heart rate and blood pressure to prepare for a fight-or-flight response. Additionally, breathing rate increases to supply more oxygen to muscles, and blood flow is diverted from non-essential functions to vital organs and muscles. These changes prime the body to react quickly to perceived threats.
Can the fight or flight instinct be traced to a physical location in human biology?
The fight or flight response is coordinated by a part of the brain called the amygdala, which is responsible for emotional processing and memory. It triggers the release of stress hormones like adrenaline to prepare the body for action in response to perceived threats. Additionally, the hypothalamus and the autonomic nervous system play crucial roles in initiating the physiological changes associated with fight or flight.
What components of the nervous system is associated with the flight or flight response?
The sympathetic nervous system originates in the spinal cord and its main function is to activate the physiological changes that occur during the fight-or-flight response.

Why is the body's response during the first stage of stress called the flight-or-flight response?
blood pressure increases hormones are released

What are 2 different physical responses which can occur during stress?
During stress, the body can respond with increased heart rate, as the sympathetic nervous system is activated to prepare for a fight-or-flight response. Another physical response can be shallow and rapid breathing, as the body takes in more oxygen to fuel the muscles and brain for quick action.
What physical reaction results from stress rather than from physical injury or illness?
One physical reaction to stress is the activation of the body's fight or flight response, which can include increased heart rate, tensed muscles, and elevated levels of stress hormones like cortisol and adrenaline. These physiological changes prepare the body to respond to a perceived threat or challenge.
Can the fight or flight instinct be traced to a physical location in human biology?
The fight or flight response is coordinated by a part of the brain called the amygdala, which is responsible for emotional processing and memory. It triggers the release of stress hormones like adrenaline to prepare the body for action in response to perceived threats. Additionally, the hypothalamus and the autonomic nervous system play crucial roles in initiating the physiological changes associated with fight or flight.
3 things that happen in the body as part of the stress response?
During the stress response, the body activates the sympathetic nervous system, leading to the release of adrenaline and cortisol. This results in increased heart rate and blood pressure to prepare for a "fight or flight" reaction. Additionally, energy stores are mobilized, and digestion is temporarily suppressed to prioritize immediate survival needs. These physiological changes enhance alertness and physical performance in response to stressors.
What physical contributing factors associated with stress reaction?
Physical contributing factors associated with stress reactions include hormonal changes, such as increased cortisol and adrenaline levels, which prepare the body for a "fight or flight" response. Additionally, muscle tension and cardiovascular changes, like elevated heart rate and blood pressure, can occur. Chronic stress may lead to fatigue, digestive issues, and weakened immune function, further exacerbating the body's stress response. Overall, these physiological changes can significantly affect both physical and mental well-being.
What causes breathing increase during a fight or flight response?
It is caused by the neurohormone called norepinephrine.
