PHYSIOLOGICAL REACTION Meaning and
Definition
-
Physiological reaction refers to an involuntary response that occurs in an organism's body as a result of external stimuli or internal processes. It involves the physiological changes and adaptations that take place to maintain homeostasis, or a stable internal environment, in response to a particular stimulus.
These reactions can occur in various systems of the body, such as the nervous system, endocrine system, cardiovascular system, and respiratory system. They can be triggered by a wide range of stimuli, including physical threats, emotional stress, temperature changes, chemical imbalances, or changes in the environment.
One common example of a physiological reaction is the fight-or-flight response, which is triggered in situations of perceived danger or threat. In this response, the body releases stress hormones like adrenaline and cortisol, leading to increased heart rate, heightened alertness, dilation of blood vessels, increased blood pressure, and enhanced strength and speed. These changes prepare the individual for either confronting the threat or escaping from it.
Other physiological reactions may include blushing, sweating, increased breathing rate, shivering, pupil dilation, changes in digestion, and alterations in hormone levels. These reactions are essential for survival and maintaining optimal functioning of the body in response to various external and internal challenges.
In summary, a physiological reaction refers to the automatic and involuntary changes that occur within an organism's body in response to a specific stimulus, aiming to maintain equilibrium and ensure appropriate responses to different situations.

Etymology of PHYSIOLOGICAL REACTION
The etymology of the word "physiological" can be traced back to the Greek words "physis" meaning "nature" and "logos" meaning "study" or "knowledge". Therefore, "physiological" refers to the study or knowledge of nature.
The word "reaction" comes from the Latin word "reagere", which consists of "re-" meaning "back" and "agere" meaning "to act". Thus, "reaction" refers to an action that occurs in response to a stimulus or event.
When we combine the two words, "physiological reaction" refers to an action or response that occurs within the body as a result of a stimulus or event, based on the understanding of nature and how the body functions.
