Canopic jars were used by ancient Egyptians to hold mummified remains. During the mummification process the organs of the human body were removed and preserved separately in canopic jars.
The Canopic Jars were decorated with the heads of the four sons of Horus. Each canopic jar guarded a different organ.
1. Imsety had a human head, protected the liver.
2. Qebehsenuf had the head of a falcon and guarded the intestines.
3. Hapy had a baboon head protected the lungs.
4. Duamatef had the head of a jackal, and guarded the stomach.
The four canopic jars were put into a special chest which went into the tomb with the mummy
