Appendix is a small worm like structure attached to the cecum.
The beginning of the colon, on the lower right side of abdomen. During first few years of life, appendix functions as part of the immune system, but after that it does not have any known function. Sudden inflammation of appendix is known as Appendicitis- and if you are able to recognize its symptoms, you can prevent serious appendicitis complications from occurring. The most serious complication of appendicitis is an infection of the lining of your abdominal cavity (peritonitis). This may occur if your appendix ruptures (perforates) and the contents of your intestines and infectious organisms invade the peritoneal cavity. Peritonitis is a medical emergency requiring immediate appendix treatment via surgery.
