Pathology is the study and medical diagnosis of disease, especially after death. Techniques include dissection, microscopic examination of tissues and chemical analysis of fluids. The legal setting for pathology is an autopsy, which is done to discover the cause of death. A person who does this work is called a pathologist.
Pathology is a science that concerns with finding the cause (etiology) or presence of a disease by careful examination of a tissue or sample of any component of the body by scrutinizing it.
