NUR 2063 ESSENTIALS OF
PATHOPHYSIOLOGY
EXAM 1 STUDY GUIDE REVIEW;
Chapter 2
What is Pathology? The study and diagnosis of the disease through examination of organs,
tissues, cells and body fluids
What is Physiology? The study of the mechanical physical and biochemical functions of
living organisms
What is Pathophysiology? THE SUUDY OF ABNORMALITIES IN PHYSIOLOGIC
FUNCTIONG OF LIVING BEINGS
What is the framework for Pathophysiology?
Etiology – The study of the causes or reasons for phenomena, identification of the cause
factors disease
Pathogenesis- The development or the evolution. How did the disease actually evolve?
Begin? Manifestations?
Clinical Manifestations- They are observed signs of the disease EX: increase in WBC
Implications/Treatments- An understanding of the etiology, pathophysiology and
pathogenesis, determine what will help. What treatment?
Homeostasis & Allostasis
What is Homeostasis? Remaining stable, set point, equilibrium, systems are in balance
What is Allostasis? Ability to successfully adapt to challenges. A dynamic process trhat
maintains or reestablishes homeostasis
Stress and Disease - Hans Selye- the pioneer in the study of stress and disease, described
stages of adaptation to a stressful event:
Alarm :Hypothalamus Activates corticotropin, fight or flight response as the result of
stressful stimulus. Internal/external HPA- Hypothalamus Pituitary Adrenal Axis
Resistance: Activity of the nervous and endocrine system in returning the body to
homeostasis.
Hypothalamus secretes corticotropin releasing hormone CRH. Activates Anterior
Pituitary
Secretes ACTH Adrenocorticotropic Hormone
Recovery OR Exhaustion: Where the body can no longer return to homeostasis,
Allostatic Overload “wear and tear on the body”
