👉 The term "appendical" refers to a small, fat organ that is located behind the lower part of the digestive tract. It is often referred to as an appendix because it appears on the outside of the stomach or intestines and can be found in some people with certain conditions such as appendicitis. Appendices are usually harmless and do not cause any discomfort or pain, but they may need to be removed if there are signs of infection or other complications.
