Finally had my critical on my 3-D plaster sculpture, where we had to display and describe the function of this organ. It was the early morning and I didn't know what to call it so it is temporary called the "Velpump", weird combination of venom and pump.
What I thought of it in a fictional realm was that it is a genetic transplant organ that attracts itself to the stomach. The Velpump serves as a filter, clearing out any toxic chemical/particles that the user that consumed then will allow the eatable substance back into the stomach. So yes, it will clean out any arsenic, food poison, bacteria, bad cholesterol and unnecessary fat for you can digest the healthy parts of any beverages and eatables.
