So what is the mesentery? It's a double fold of peritoneum - the lining of the abdominal cavity - that attaches our intestine to the wall of our abdomen, and keeps everything locked in place.
The new organ is found in our digestive systems, and was long thought to be made up of fragmented, separate structures. But recent research has shown that it's actually one, continuous organ.
The evidence for the organ's reclassification is now published in The Lancet Gastroenterology & Hepatology.
"In the paper, which has been peer reviewed and assessed, we are now saying we have an organ in the body which hasn’t been acknowledged as such to date," said J Calvin Coffey, a researcher from the University Hospital Limerick in Ireland, who first discovered that the mesentery was an organ.
