In a recent study, researchers at Duke University Medical Center, USA, said Appendix serves as protection of body against of harmful germs and protect the saprophytic bacterial flora (which is found normally in the digestive tract). Until now most doctors and scientists believe that the appendix is an organ that has not a very precise role, being practically useless.
After closing the study, researchers concluded that saprophytic bacteria in the appendix, which help to digest food, can survive after an episode of diarrhea, that almost totally cleans intestine, favoring its repopulation with saprophytic bacteria, following diarrhea episode.
Appendix is located in the place where the small intestine joins the large intestine, is mobile and has a length of 3-5 cm. It's role was the subject of scientific community debate for many years. It was recently demonstrated the presence of lymphoid tissue at this level.A variety of bacteria that help the digestive system to digest food is present at this level. The gut rewards those bacteria through the food made available and protection against harmful factors. Researchers believe that immune system cells located in the Appendix have a protective function for the saprophytic bacteria.
