, Introduction
• Pathophysiology is a term that combines the
words pathology and physiology.
Pathology: Pathos means disease, i.e. is the
science which deals with the study of
structural and functional changes in cells,
tissue and organs of the body that cause or are
caused by disease.
Physiology deals with the function of the
human body.
Thus pathophysiology deals with the effect of
the changes in cells or organs that occur with
diseases on total body function. (Example:
traumatic injury causes atrophy of the brain
and degeneration of neurons in the brain
resulting in Alzheimer’s disease)
Or it may be defined as the physiology of
altered health
