Post-mortem examination of animals (necropsy, autopsy) is a diagnostic procedure aimed at finding out the cause of death of an animal, as well as determining the spectrum of macroscopically visible changes in organs and tissues of cadaver. In scientific and research practice, one of the key stages of the experiment and at the same time a humane experimental point often is euthanasia of animals with subsequent pathoanatomical and histological examination of organs. From the point of view of the quality and reliability the obtained data, an important step is the standardization of the procedure to dissection and extracting organs of laboratory animals. A series of articles about the carrying out of necropsy of laboratory animals will highlight the main stages of autopsy. In this work, a technique to dissection and extracting organs of rats is described.
