.....Writing in The Lancet Gastroenterology & Hepatology, scientists have officially announced the discovery of a new organ inside the human body. That’s right, there’s a brand new organ hiding in our abdomen and it’s only just been classified.
Known as the mesentery (meaning “in the middle of the intestines”), it can be found in our digestive systems. Leonardo da Vinci actually gave one of the first descriptions of it back in the day, but until around 2012 it was thought to be a series of separate structures keeping the intestines attached to the abdominal wall, like a series of support girders.
