Introduction to Pathology
three causes of death
1.) deaths due to disease causing microorganism. 2.) deaths due to degenerative pathological disorders like heart disease or stroke. 3.) deaths due to by products of the social environment such as suicide, homicide, or accidents.
Microscopic Patahology
also known as cellular or histo- pathology, studies changes which occur in cells of the body at the microscopic level.
disease
any change in the structure of function of the body as a result of injury to the tissues.
autopsy involves
both the gross examination of the human body and its organs and tissues plus microscopic examination of tissues samples and cells which have been removed for further study.
cavitation
caused by the path of the bullet itself combined with the continues forward acceleration of the tissue in the wake of the bullet. over 1,000 feet per secound
cocaine
causes heart to beat improperly, water soluble powder, produces a euphoric high.
benefits of autopsy
confirm, alter diagnosis; and provide evidence os substance; Also find other evidence; provided knowledge; helps in legal situations; helps survivors.
general pathology
deals with general or broad disease processes, such as necrosis or inflammation, which may affect the entire body or wide spread tissues and organs.
clinical pathology
deals with the laboratory study of, and the performance of standardized test on, body fluids, and secretions such as blood and urine tests or cultures and smears of various types.
pathological anatomy
deals with the study of tissues which have been removed from the body for pathological study.
manner of death
explains how the cause of death came about.
postmortem examination
from latin words for after and death

patho

heroine
is an opiate, from poppy plant, causes heart or respiratory failure. causes sedation.
pathogenesis
is the mechanism that results in the manifestations of signs and symptoms in the body.
mechanism of death
is the physiological derangement produced by the cause of death that results in death.
trauma
is the process of event leading to an injury or wound.
laceration and crushing
low velocity bullets that travel less than 1,000 feet per second. handguns
ology
means the study of.
etiology
or underlying causes of disease.
physiological pathology
refers to studying the functional changes in the body resulting from disease.
ballistics
refers to the science of the travel of bullets in flight.
gross pathology
studies changes in the structure and function of the body which can be observed with the unaided eye.
special pathology
studies disease processes affecting individual body areas or systems, such as pathology of the respiratory system or disease of the skin.
surgical pathology
study of tissues specimens excised surgically during operation.
medical - legal pathology
that field of pathology which deals with both the medical and legal issues surrounding death.
pathology
the study of disease- specifically the study of the structure and function of the body as it is affected by disease.
shock waves
tissues are compressed, last only a few microseconds causing little tissue damage at low velocity.
