Scientists have learned a lot about how the human body works, but our biology remains a mystery in many ways. Researchers have discovered what they’re calling a “new organ” within the human digestive system ― a reminder of just how much uncharted territory remains to be discovered within us.
The discovery of the body’s 79th organ prompted an update to the famous Gray’s Anatomy textbook, which is used by medical students around the world.
People have known about the newly classified organ, known as the “mesentery,” for hundreds of years ― Leonardo DaVinci even included it in an anatomical illustration. However, it was thought to be a fragmented structure consisting of separate parts until Dr. J. Calvin Coffey, a professor of surgery at the University of Limerick in Ireland, found evidence that it was one continuous organ.
Based on his findings, outlined in a paper published in November in The Lancet Gastroenterology & Hematology, Coffey argues that “mesenteric science” should be its own specialized field of medical study.
The mesentery connects the intestines to the digestive tract. More specifically, the organ is a double fold of connective tissue arising from the peritoneum ― the membrane lining the abdominal cavity that attaches the stomach, small intestine, pancreas, spleen and other organs to the posterior abdominal wall.
