First, the brain and organs were removed. A hook was used to pull the brain out through the nostril. The brain was discarded as the ancient Egyptians believed the heart was the center of thought and emotion.
Next, the internal organs were removed through a small cut in the side of the stomach. The liver, lungs, stomach, and intestines were placed in canopic jars. The heart was wrapped and left inside the body, to be weighed in the afterlife.
