At the time of death, all tissue rapidly begins to degrade. In order to ensure the greatest research and diagnostic value for the brain tissue, it is essential that it is removed as quickly after death as possible.
Autopsy. During the course of the autopsy, various laboratory tests may be undertaken, including x-rays, retention of body fluids such as blood and urine and small samples of tissues such as liver or brain for toxicological analysis and cultures of body fluids and organs for evidence of infection.

1. Complete autopsy is defined to include a detailed external examination of the entire body, and an internal examination to include the removal and dissection of all thoraco-abdominal and neck organs, opening the head with the removal and examination of the brain. 2.1.
Major Organs. Organ removal—Using special techniques, the organs are cut and removed from the body.

They are weighed, washed, and dissected as necessary.
The autopsy process
To release the body to the family as soon as possible, the autopsy is usually performed the day following the death and almost always within three working days.
Putrefaction (4-10 days after death) – Autolysis occurs and gases (odor) and discoloration starts. Black putrefaction (10-20 days after death) – exposed skin turns black, bloating collapses and fluids are released from the body.
Autopsies usually take two to four hours to perform. Preliminary results can be released within 24 hours, but the full results of an autopsy may take up to six weeks to prepare.
Although State laws vary in specific requirements, deaths that typically require investigation are those due to unusual or suspicious circumstances, violence (accident, suicide, or homicide), those due to natural disease processes when the death occurred suddenly and without warning, when the decedent was not being ...
