What Is The Body's Response To Emergency

The human body reacts externally or internally in the way of physiological responses. When we experience one of these stressors the physiological responses job is to prepare the body to deal either by adapting to it or simply surviving it. This can promote a functional alteration in the organs normal function.

In Prospero 's case in Masque of the Red Death Prince Prospero, was faced with the threat of survival, surviving the Red Death, a plague sweeping his kingdom killing all it comes into contact with. 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. The combined effects of these two systems are the fight-or-flight response.When the hypothalamus tells the sympathetic nervous system to kick into gear, the overall effect is that the body speeds up, tenses up and becomes generally very alert. If there 's a burglar at the door, you 're going to have to take action fast. The sympathetic nervous system sends out impulses to glands and smooth muscles and tells the adrenal medulla to release epinephrine and norepinephrine into the bloodstream. These "stress hormones" cause several changes in the body, including an increase in heart rate and blood pressure.At the same time, the hypothalamus releases corticotropin-releasing factor into the pituitary gland, activating the adrenal-cortical system. The pituitary gland secretes the hormone ACTH (adrenocorticotropic hormone). ACTH moves through the bloodstream and ultimately arrives at the adrenal cortex, where it activates the release of approximately thirty different

When the sympathetic nervous system kicks into gear, the body speeds and tenses up, and, overall, becomes extremely alert. It then sends out impulses to glands and smooth muscles, while alerting the adrenal medulla to release the stress hormones, norepinephrine and epinephrine, into the bloodstream. At the same time, the hypothalamus releases the corticotropin-releasing factor (CRF)

Stage1- Alarm stage is the immediate response to the stressor. This immediate response will result in a person's sympathetic nervous system being stimulated. The stimulation of the person's sympathetic nervous system is characterized by the increase in one’s heart rate, blood pressure, and respirations. This reaction is also known as a fight or flight response when adrenaline is released in a person body which stimulates the sympathetic nervous system. This stage gives us the strength to fight off a threat.

It is also called as the vegetative system composed of sympathetic and parasympathetic system. Since the sympathetic system fires up the body it is therefore the sympathetic system that prepares our body for action. It plays an important part in the perception of the stimulus presented. In the case of resilience or acute stress, its reaction includes: cardiac contractions, sweating, stimulating of hair follicles, dilation of respiratory organs, and redirection of blood supply to muscles (Ortega and Saavadra, 2014).

After a person is exposed to a stressor, the person enters the alarm phase. Here, initial shock occurs and sympathetic arousal is prolonged by adrenaline/epinephrine and nor epinephrine. The results include the following: increased heart rate, increased blood flow to the

If there is one thing that humanity is not immune from, it is stress. “Hans Selye (1979) defined stress as the nonspecific response of the body to any demand made upon it” (Kalat, 2013, p. 380). Initially, changes in the biological responses occurring in the body during times of stress allowed for evolutionary advantages across populations. In the fight-or-flight response, for example, the parasympathetic nervous system initiates the body’s preparedness

Adrenaline now comes into play because of high activity in the brain. The pituitary senses all of the firing neurons and releases hormones that signal to the adrenal glands to release adrenaline. This causes your heart to beat faster,

Stress may be a traditional physical response to events that create USA feel vulnerable or upset our balance in a way. once a threat is perceived, our systema nervosum responds by emotional a flood of stress hormones, as well as epinephrin and Hydrocortone. These hormones rouse the body for emergency action. As a result, our heart pounds quicker, muscles tighten, pressure rises, breath quickens, and senses become chiseler.

First, our nerves respond by detemining a situation and deciding if it is stressful. This decision is made based on sensory input. By processing the things we see and hear and in stored memories. Also, what happened the last time we were in a similar situation. If the situation is judged as being stressful, the hypothalamus is activated. The hypothalamus in the brain is in charge of the stress response. When a stress response is triggered, it sends signals to two other structures: the pituitary gland, and the adrenal medulla. These short term responses are produced by The Fight or Flight Response via the Sympathomedullary Pathway.(SAM) Long term stress is regulated by the Hypothalamic Pituitary-Adrenal (HPA) system. This is what happens: The

Adrenaline is a hormone that the adrenal glands produce. They are produced during times of stress or excitement. This is a powerful hormone that is a part of the body's flight or fight response. It works by diluting air passages, contracting blood vessels and stimulating the heart. This helps supply the lungs with more oxygen and increase blood flow to the muscles.

According to www.health.harvard.edu, “These glands respond by pumping the hormone epinephrine (also known as adrenaline) into the bloodstream. As epinephrine circulates through the body, it brings on a number of physiological changes.” The heart rate and blood pressure increases resulting in an increase in oxygen and nutrients that reaches the brain and muscles. Liver is stimulated to release glucose into the blood stream providing more energy that is used to power the muscles. Saliva production decreases as the stomach does not move for digestion, nor release secretions. Bronchioles in the lungs is dilated to allow more air into the lungs, which would increase oxygenation in the blood and keeps the increase flow to the lungs due to increased heart rate. Pupils in the eyes dilates because of being surprised, sweat glands increase secretion, the sphincter contracts and the bladder to relax

Shock events or disaster often cause communities to cease functioning properly. Emergency management is planned to prepare communities for these events, mitigates their effects, and responds to and recovers from these events. Part of emergency management, the recovery phase, aims to return the communities to the normal situation, or an even safer situation following the shock events. The recovery phase requires an understanding and exploitation of the dynamic interactions among the community’s physical and social infrastructures and post-response condition. Case studies of recovery processes and effects, combined with the understanding of the dynamic interactions can help in improving the process of recovery phase in the future. The purpose

In the alarm stage, the body encounters a stressor. The stressor will cause the body to react with the fight or flight response.Next, the nervous system and hypothalamic-pituitary-adrenal axis will be

In order to conduct this study, Latane and Darley found subjects by contacting male Columbia college students by phone. Once they arrived they were directed to a waiting room where they had to complete a questionnaire. Next, experimental manipulation occurred in which the subjects were randomly split into groups. Some subjects were alone, others were part of a three person group with one subject and two confederate subjects that acted like “undercover” participants, and the last group was three inexperienced subjects. Then, a critical situation occurred as soon as subjects completed two pages of the questionnaire. The experimenter introduced smoke through a small vent. The behavior as well as communication between the subjects was observed
