What is GAS- General Adaptation Syndrome?
A chain or pattern of physiological events that occur throughout the body. It is the body's response to stress. Global adaptation.
Essentially, what occurs during GAS (general adaptation syndrome)?
During GAS, the body's response is the release of certain hormones and subsequent changes in the structure and chemical composition of the body.
What parts of the body are affected by stress?
Parts of the body particularly affected by stress are the gastrointestinal tract (GI), the adrenal glands, and the lymphatic structures.
What is LAS- Local Adaptation Syndrome?
The body's reaction to stress, locally. Such as one organ or a part of the body reacting alone.
What are the 3 stages of GAS and LAS?
- Alarm Reaction
- Stage of Resistance
- Stage of Exhaustion
List the details of Alarm reaction with its 2 parts:
Alarm reaction is when the body reacts to a stressor. During the Shock Phase, the stressor stimulates the Sympathetic Nervous System. Adrenal medulla secretes Epinephrine and Nor-Epinephrine.
Secretion of Epi results in Tachycardia, increase Myocardial Infarction, increase Bronchial Dialation, increase Blood Clotting, increase Metabolism.
Secretion of Nor-Epi results in decreased blood to kidney, increase in renin.
Secretion of Cortisone, hyperglycemic.
During Countershock, everything that occurs during Shock phase is reversed.
What occurs during Stage of Resistance?
Stage of Resistance is when the body's adaptation takes place.
What occurs during the Stage of Exhaustion?
During the Stage of Exhaustion, the adaptation that the body made during the Stage of Resistance cannot be maintained, the ways used to cope w/ stressor have been exhausted. At the end the body either rests and returns to homeostasis or death occurs.

List some Defense mechanisms:
- Reaction Formation
