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.
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.
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.
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.
Walter Cannon, a harvard physiologist, first investigated the fight or flight response in 1927.
The opposite of the fight-or-flight response is often referred to as the "rest and digest" response, governed by the parasympathetic nervous system. This state promotes relaxation, recovery, and conservation of energy, allowing the body to focus on maintenance functions such as digestion and immune response. While the fight-or-flight response prepares the body to confront danger or flee from threats, the rest-and-digest response encourages calmness and restoration.

Your eye dilates
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.
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.
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.

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.
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.
The ALARM 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.
The adrenal medulla is responsible for the fight-or-flight response. It releases a hormonal cascade that results in the secretion of epinephrine and nonrepinephrine.
