Why do we have an appendix? What does the appendix do?
I'm going to convince you in this video that the appendix is a badass little organ.
YES! It has a function!
As a surgeon one of the most common operations I do every week is a laparoscopic appendectomy...removing a child's appendix.
Very often I'm asked the questions...why do we have an appendix? What is the appendix? What does the appendix do?

DOES THE APPENDIX DO ANYTHING?
Incorrectly many people think the appendix is just a left over, that it has no function or that it has no purpose.
Wrong.
The appendix DOES have a function, both an immune function and a digestive function.
For example, the appendix sees little feces and is a storage warehouse for healthy commensal bacterial. After a diarrhoeal illness the appendix helps us repopulate the microbiome.
The appendix has a significant immune function with secretory IgA and IgG and helps create a healthy biofilm in the colon.
So don't just chop out the appendix to chop it out!
We're going to cover a few clinical cases as well and at the bottom of the description I'll put the answers so you can check yourself!
