    2. Homeostasis What is homeostasis????? Homeostasis is an (ideal or virtual) state of equilibrium, in which all body systems are working and interacting in an appropriate way to fulfill all the needs of the person and/or the body. When homeostasis is interrupted (e.g. by response to a stressor), the body tries to restore it by adjusting one or more physiological processes. This stress-adaption mechanism includes activation of the Hypothalamic-Pitauitary-Andrenal Axis (HPA Axis) with the autonomous nervous system and endocrine reactions of the body. Severe stressors or long lasting adjustment demands can cause severe imbalance of this steady state. This might cause not only psychological distress but also psycho-somatic disorders.

    3. Shock Can occur when any part of the cardiovascular system does not function properly for any reason Begins with abnormal cellular metabolism that occurs when too little oxygen is delivered to tissues Shock is a condition in which a systemic decrease in perfusion to tissue and organs leads to poor gas and nutrient exchange. Delays in recognition and treatment can lead to irreversible shock, multisystem organ failure, and death. Types of shock and their causes vary because shock is a manifestation of a pathologic condition rather than a disease state. More then one type of shock can be present at one timie

    4. Process of Shock Initial stage (early shock) Nonprogressive stage (compensatory stage) Progressive stage (intermediate stage) Refractory stage (irreversible stage)
