Then they will look at the internal body (after cutting it) to get a closer look at why the person died. They will take out all the organs and weigh and measure them to see if they are within the regular measurement and weight requirements, they will take pieces of each organ and cut it to be further tested. For example, if it is assumed that a person died of a overdose, the medical examiner will take each organ and test it to see what kind of drugs were in the person’s system at the time of death.
