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 else can I help you with?
Which of the following is true of the sympathetic nervous system?
The sympathetic nervous system is responsible for the "fight or flight" response, which prepares the body for action in times of stress. It increases heart rate, dilates airways, and redirects blood flow to vital organs.
What is the other name for fight or flight response?

What is plasma epinephrine effect?
Plasma epinephrine, also known as adrenaline, has a variety of effects on the body. It can increase heart rate, blood pressure, and blood glucose levels, preparing the body for a "fight or flight" response. Epinephrine also dilates airways to improve breathing and increases blood flow to muscles.
Who first described the fight or flight response?
Walter Cannon, a harvard physiologist, first investigated the fight or flight response in 1927.
What hormone is responsible for the fight or flight response?
The sympathetic nervous system is responsible for the fight of flight response. The the adrenal glands release epinephrine in the fight or flight response, and norepinephrine after the threat ceases.

What is the consensual response when a light is shone in eye?
Your eye dilates
What is released into the bloodstream when one's breathing and heartbeat increases?
When released into bloodstream, epinephrine increases heart rate, constricts blood vessels, dilates air passages and participates in the fight-or-flight response of the sympathetic nervous system. Norephinephrine does the same and increases the brain's oxygen supply.
What layer dialates the pupil?
The layer that dilates the pupil is the iris, which is the colored part of the eye. Within the iris, the dilator pupillae muscle is responsible for widening the pupil in response to low light conditions or during the fight-or-flight response. This process is controlled by the sympathetic nervous system.
What is the function of the sympathetic nervous system in the body's stress response?
The sympathetic nervous system is responsible for activating the body's fight-or-flight response during times of stress. It increases heart rate, dilates airways, and releases stress hormones like adrenaline to prepare the body to react quickly to perceived threats.
Which of the following is true of the sympathetic nervous system?
The sympathetic nervous system is responsible for the "fight or flight" response, which prepares the body for action in times of stress. It increases heart rate, dilates airways, and redirects blood flow to vital organs.
What effects on the human body does adrealine have when the body is healthy?
Adrenaline increases heart rate, dilates air passages in the lungs, increases blood flow to muscles, and triggers the release of glucose for energy. These effects help prepare the body for a "fight or flight" response to stress or danger.
What is the other name for fight or flight response?
I don't think there is because fight or flight is response action the body makes when in a dangerous situation. Stand and fight or flight RUN.
What is the role of epinephine?
Epinephrine, also known as adrenaline, plays a crucial role in the body's fight or flight response. It increases heart rate, constricts blood vessels, dilates air passages, and increases blood flow to muscles. This hormone helps prepare the body to respond to stress or danger.
Which stage in stress response does the fight or flight response occur?
The ALARM response

What is the fight or fight response?
The fight or flight response is an automatic thing that happens to the human body when it is faced with danger at intense levels. You will automatically run away or fight the danger.
