What’s the real function of the appendix in modern humans?

I’ve always heard that the appendix is a vestigial organ, but I’ve also read some articles suggesting it might have a role in the immune system or gut health. Does anyone have up-to-date info on what the appendix actually does in our bodies today? Is it really just a leftover from evolution, or does it have a function we’re only now starting to understand? Curious to hear from anyone with expertise or recent research on this!

The classic view is that the appendix is vestigial, but some newer studies suggest it might help maintain gut flora or play a role in the immune system, especially in kids. Still, people live just fine without it.

I had my appendix out as a teen and haven’t noticed any difference. But I’ve read that it can act as a “safe house” for good bacteria, helping repopulate the gut after infections. Not essential, but maybe not totally useless either.

It’s still a bit of a mystery! Some evolutionary biologists think it was more important for digesting tough plant material in our ancestors. Now, it seems to have a minor immune function, but nothing we can’t live without.
