Explanation Three systemic stages are incorporated by the non-specific physiologic response toward stress. They are alarm, resistance, and exhaustion and are the key features of the Selye’s general adaptation syndrome. The alarm stage is a type of fight or flight mechanism that is involved in triggering the body for physical activity. It allows the body to defend itself against potential threats. This stage is initiated by the hypothalamus and senses a requirement to activate the GAS in response to the stressors. The second stage is a resistance stage in which the stress response of the body is characterized by a decreasing level of the stress...

Summary Introduction

To explain: The key features of Selye’s general adaptation syndrome.

Introduction: General adaptation syndrome (GAS) is a three-stage process. It describes how the body undergoes certain physiological changes when it is under stress. In 1936, the theory of GAS was developed by a medical doctor and researcher Hans Selye. He described three predictable changes in which the body responds against the stressors.
