The presence of lymphoid tissue suggests that the appendix may play a role in the immune system in addition to the digestive system. What Does the Appendix Do? The appendix is not a vital organ and medical researchers still debate its exact function in our bodies. One hypothesis suggests that it is a vestigial remnant of a once larger cecum. This larger cecum would have been used by vegetarian ancestors to digest cellulose from plants.
The role of the Appendix is still a mystery to science, but some recent research has led some scientists to believe it is part of the fetal endocrine system, helping to supp â¦ ort the homeostasis of the fetus. This is not the case after birth, and the appendix starts to fill with lymphoid tissue. This has given scientists the idea that the Appendix is part of the Immune System.
