1 The study of disease, its essential nature, cause, and development; and the structural and functional changes it produces 2 A condition which which might lead to sickness, disability or death No pathologies have been discovered which are strongly associated with subsequent SIDS deaths
the branch of medical science that studies the causes and nature and effects of diseases any deviation from a healthy or normal condition
study of the nature of disease, especially how a pathogen produces disease by altering host physiology
Pathology is the study of the way diseases and illnesses develop. the study of the causes and effects of illnesses (pathologia, from pathos ( PATHOS)). Medical specialty dealing with causes of disease and structural and functional changes in abnormal conditions. As autopsies, initially prohibited for religious reasons, became more accepted in the late Middle Ages, people learned more about the causes of death. In 1761 Giovanni Battista Morgagni (1682-1771) published the first book to locate disease in individual organs. In the mid-19th century the humoral theories of infection were replaced first by cell-based theories (see Rudolf Virchow) and then by the bacteriologic theories of Robert Koch and Louis Pasteur. Today pathologists work mostly in the laboratory and consult with a patient's physician after examining specimens including surgically removed body parts, blood and other fluids, urine, feces, and discharges. Culturing of infectious organisms, staining, fibre-optic endoscopy, and electron microscopy have greatly expanded the information available to the pathologist
The study of the nature of disease and its resulting structural and functional changes
The study and interpretation of changes in organs, tissues, cells, and alterations in the body chemistry that aids in the diagnosis and treatment of disease
the scientific study of the nature of disease and its causes, processes, development, and consequences
Pathology is the study of disease processes with the aim of understanding their nature and causes This is achieved by observing samples of blood, urine, feces, and diseased tissue obtained from the living patient or from an autopsy, by the use of X-rays and by many other techniques
The medical science, and specialty practice, concerned with all aspects of disease, but with special reference to the essential nature, causes, and development of abnormal conditions, as well as the structural and functional changes that result from the disease processes
The study of disease Pathologists tend not to work with living patients, but with specimens of tissue or blood which are analyzed in order to provide information that will benefit the patient Pathologists oversee the labs where blood tests are run and look at specimens from biopsies under microscopes to diagnose diseases like cancer Pathologists also do autopsies on cadavers to find the cause of death
The study of disease through examination of body tissues and organs This always includes a microscopic examination Any tumor suspected of being cancerous must be diagnosed by pathologic examination
The study of disease by the examination of tissues and body fluids A doctor who specializes in pathology is called a pathologist The pathologist examines biopsy specimens and determines if cancer cells are present
