The embalmers who mummified pharaohs and nobles took seventy days.
Mummification was a combination of embalming, saying the correct prayers and going through the correct rituals.
The embalmers first made a cut into the left side of the body with a flint knife (remember most of ancient Egyptian times were in the Stone Age!) and through this they removed the intestines, liver and lungs. These were dried out and stored in special vessels called canopic jars. The brains were pulled out through the nose using a long hook. The heart is not removed because it belongs with the body.
