Population density shows how cramped or spread out inhabitants are. Cities with high population densities can be considered overpopulated, but the extent to which this is the case depends on factors like quality of housing and infrastructure and access to resources. Source: Wikipedia, 2017.
Livor mortis on the posterior aspects of the body is caused by settling of the blood because of gravity when the body is in a supine position. As the postmortem interval lengthens, Tardieu spots develop in areas of lividity, such as this individual's shoulder area, as decomposing capillaries rupture.
In some cases, chylothorax may be caused by trauma or by increased pressure within the thoracic duct or vena cava. Trauma may cause the thoracic duct to rupture or become 'leaky'. Automobile injuries or falls from a tree or window that injure the chest cavity are the most common causes of traumatic chylothorax.
