Pathology Final ALL CARDS Flashcards
Study of disease
Pathology
any abnormal condition which impairs the normal functioning of the body. Local disease and genetic diseases can occur.
Disease
was the leading cause of death in the early 1900’s
TB
the leading cause of death TODAY
CVD- Cardiovascular Disease
Another name for CAUSE
Etiology
The cause of disease is divided into what 2 categories?
Immediate (exciting) &Predisposing
The beginning of disease. The manner in which a particular disease develops.
Pathogenesis
3 parts of disease that we study
- Cause (Etiology) 2. Pathogenesis 3. Changes and final effects brought about in the body.
Study of general disease processes, such as inflammation, degeneration, necrosis (localized area of dead tissue in a living body), repair (i.e.: scar tissue), etc.
General Pathology
The body’s total response to any injury
inflammation
Study of disease in relation to a particular organ or the organs system. Ie., disease of the digestive track.
Special Pathology
5 Divisions of Pathology
- Pathological Anatomy (Morbid Anatomy) 2. Surgical Pathology3. Clinical Pathology 4. Medico - Legal Pathology (forensic pathology) 5. Physiological Pathology
The study of the structure of the human body as affected by disease.
Pathological Anatomy (Morbid Anatomy)
localized area of dead tissue in a living body
necrosis
Study of disease by means of biopsies.
Surgical Pathology
The study of disease by means of:body secretions (useful substances produced within the body), body excretions (waste substances rid from the body), & other body fluids.
Clinical Pathology
Legal Pathology (forensic pathology) the study of disease, death, and injuries with medical/legal potential.
Medico
2 methods to study Pathological Anatomy (Morbid Anatomy)
1.) Gross Inspection 2.) Histopathology
See changes of the structure of the body with the unaided eye.
Gross inspection
A study of the structure of the cell as affected by disease, by means of microscope. Disease at cellular levels.
Histopathology
The study of the functions of the body as affected by disease.
Physiological Pathology
A study of disease by samples of tissue removed surgically from a living person.
Biopsy
useful substances produced within the body
body secretions
waste products that are rid from the body
body excretions
The study of deaths and injuries of medical and legal significance
Medico-Legal Pathology
