if I ingest (for example) a pebble in the middle of the food, which would be carried out through the Rectum/Anus, passing through the Colon, in the Feces, could it instead end up in the Appendix? it’s possible?

I know, it might be an unpleasant question, but my interest is concerning the functioning of the Appendix organ, because I have looked for official references on this on the internet and have not found any.
