Is the blood drained from the body before cremation?
If a body is embalmed before cremation, the bodily fluids are exchanged (drained, and then replaced) with chemicals during the embalming process. These chemicals are also fluid. But the body is not drained prior to cremation, whether or not an embalming has taken place.
Why do dead bodies turn blue?
Lividity is the bluish-purple discoloration of skin after death. It is a sign of livor mortis and occurs when blood pools at the lowest point of the body due to gravity and loss of blood circulation.
Do morticians remove eyes?
We don’t remove them. You can use what is called an eye cap to put over the flattened eyeball to recreate the natural curvature of the eye. You can also inject tissue builder directly into the eyeball and fill it up. And sometimes, the embalming fluid will fill the eye to normal size.
