The appendix has been identified as an important component of mammalian mucosal immune function, particularly B cell mediated immune responses and extrathymically derived T cells. This structure helps in the proper movement and removal of waste matter in the digestive system, contains lymphatic vessels that regulate pathogens, and lastly, might even produce early defences that prevent deadly diseases. Additionally, it is thought that this may provide more immune defences from invading pathogens and getting the lymphatic system's B and T cells to fight the viruses and bacteria that infect that portion of the bowel and training them, so that immune responses are targeted and more able to reliably and less dangerously fight off pathogens. In addition there are different immune cells called innate lymphoid cells that function in the gut, to help the appendix maintain digestive health. <ref>[https://en.wikipedia.org/wiki/Appendix_(anatomy) Appendix]</ref> | The appendix has been identified as an important component of mammalian mucosal immune function, particularly B cell mediated immune responses and extrathymically derived T cells.

==Appendicitis== | |||
Appendicitis is a condition characterized by inflammation of the appendix. Pain often begins in the center of the abdomen, corresponding to the appendix's development as part of the embryonic midgut. This pain is typically a dull, poorly localized, visceral pain.As the inflammation progresses, the pain begins to localize more clearly to the right lower quadrant, as the peritoneum becomes inflamed. This peritoneal inflammation, or peritonitis, results in rebound tenderness (pain upon removal of pressure rather than application of pressure). | |||
