Autopsy or postmortem is a medical examination of human body that is performed to know the cause, manner and duration since death. The autopsy involves complete examination of the body. The external examination gives indication of situation of the body : number of injury, color changes due to the affect of poisons. Internal examination gives indication of condition of organ in the body of deceased. For a complete internal examination dissection is required. Autopsy is complete when all four cavities like cranial, thoracic, abdominal and pelvic are open through dissection, which allows the assessment of organs present in these cavities. Opening of the intestinal cavity will give a way to assess the intestine, which can be dissected to know the contents present in it.
In marine environment, many animals confuse the plastic littering the oceans for food including sea turtles. Once in these animal bodies the plastic accumulates, and the chemicals can cause excess estrogen to be produced, which has led to discoveries of male fish with female sex organs. For sea turtles, the plastic blocks their digestive tract and the food that is trapped releases gases that render them buoyant, and unable to dive for food. The turtle was slowly starving because a single use plastic bag, which she had eaten, was blocking her digestive tract.
The plastic contains destructible and harmful agents that is not good for human and animals health.
