Answer:
Step-by-step explanation:
In ancient Egyptian mummification practices, the brain was typically left inside the body during the mummification process because it was believed to be the center of intelligence and the source of a person's thoughts and emotions. It was also believed to be necessary for the afterlife as the soul or spirit would need it to function in the afterlife.
On the other hand, the ancient Egyptians removed and discarded the heart during the mummification process as it was believed to be useless for the afterlife. They believed that the heart was weighed against the feather of Ma'at, the goddess of truth and justice, in the afterlife to determine whether the deceased was worthy of eternal life. The heart was believed to contain a person's sins and impurities, so it was removed and replaced with a heart-shaped amulet to protect the person in the afterlife.
