What is stress physiology?

stress physiology is a general term used to describe physiological reactions that various organisms experience when located in stress -inducing situations. When placing in stress situations, the body tends to experience a significant chemical and physical reaction focused on redirecting body sources to handle the source of stress. While stress physiology does not tend to be particularly effective in situations that cause stress in many modern people, it is an effective survival mechanism for organisms that have to deal with predators and other physical threats. One of the most important parts of stress physiology is known as a "combat or leaflet reaction" and includes a set of physiological changes designed to allow the body to fight or flee the threat.

combat or flight reactions are among the most commonly studied and examined aspects of stress physiology due to its prevalence in stress reactions of many organisms in different differences of the situation. In a fight or flight response with pBlood rush increases to the muscles and the respiratory system to allow increased physical activity. Metabolism increases to provide the body with a high level of usable energy. Overall, the body is optimized for fast and strong muscle and cardiovascular activity necessary to escape or fight potential threats.

Many parts of the body are largely unnecessary for combat or flight activities, so stress physiology involves reducing activity in some areas. For example, blood supply is reduced to some parts of the body, including the digestive system and some parts of the brain. The digestion of food and brain functions, such as those that allow speech, are not generally necessary during combat or flight situations.

In some cases, the different phases of physiology of stress are. After the perception of a potential threat, the animal may enter into a state of increased sensory awareness before full response to the fight or flight. UmoIt routine to determine the animal exactly whether there is a threat. After identifying the threat with certainty begins to combat or flight response, allowing the necessary rapid muscle effects.

One of the main elements of stress physiology, which facilitates combat or aircraft, is to release hormones such as adrenaline and noradrenaline. Such hormones are chemical signals that will initiate various changes in stress physiology when released into the bloodstream. Adrenaline, produced in the adrenal glands, is one of the most important chemical signals involved in the response to human stress.
