To remove the organs they would usually make a cut on the left side of the body. They would first remove the organs that decay rapidly placing them in Canopic (special boxes/jars), the organs would be buried with the body. Egyptians believed that the heart was the center of a persons being and intelligence, so they left the heart in its place.
Before the Funeral
Next they dried out the body. They placed natron packets inside the body and also covered it on the outside with natron. After the body was dried out they took out the packets and washed the natron off.
Last they would wrap the body. It took hundreds of yards of linen. To protect the dead from mishap they would write magical words/ prayers and put amulets on the linen. They often placed a mask in between wrapping the head. To finish wrapping they secured the final cloth with linen strips.
Sometime before someone's death there would be workers already making the tomb. People would place many things in side the tomb so the person could enjoy them in the afterlife. For ex: furniture, statuettes, wall paintings, and lists of food/ prayers. All of these things would become real in the afterlife through a magical process.
First the priests would perform religious rites at the tomb's entrance. Next he would touch various parts of the mummy with a special instrument so they would "open" and can enjoy the afterlife. They are ready for the afterlife when the mouth is touched. This allows them to eat and speak. Lastly, the mummy is placed in a coffin and put in the burial chamber and then the entrance is sealed.
The mummified body was home to the soul and spirit and destroying it would mean they would be lost. There are 3 different spirits the ka, ba and akh, all 3 were important to the Egyptians. Since they loved life so much they made elaborate burial places, so they could continue life after death.
