Pathophysiology

Pathophysiology is the study of the changes of normal mechanical, physical[disambiguation needed ], and biochemical functions, either caused by a disease, or resulting from an abnormal syndrome. More formally, it is the branch of medicine which deals with any disturbances of body functions, caused by disease or prodromal symptoms.

An alternative definition is "the study of the biological and physical manifestations of disease as they correlate with the underlying abnormalities and physiological disturbances."

The study of pathology and the study of pathophysiology often involves substantial overlap in diseases and processes, but pathology emphasizes direct observations, while pathophysiology emphasizes quantifiable measurements.
