Researchers have found a new organ inside our bodies, and it’s one that’s been hiding in plain sight in our digestive system this whole time.
Known as the mesentery, it was previously thought to be just a few fragmented structures in the digestive system. But scientists have realised it is in fact one, continuous organ. Although its function is still unclear, the discovery opens up “a whole new area of science,” according to J Calvin Coffey, a researcher at the University Hospital Limerick who first discovered it.
The research has been published in The Lancet medical journal. Following its reclassification, medical students are now being taught that the mesentery is a distinct organ. Gray’s Anatomy, the world’s most famous medical textbook, has been updated to include the new definition.
Medical students and researchers can now investigate what role the mesentery might play in abdominal diseases, which it is hoped could ultimately lead to new treatments. The organ is a double fold of peritoneum – the lining of the abdominal cavity – that holds our intestine to the wall of our abdomen.
Although there are generally considered to be five organs in the human body, there are in fact now 79, including the mesentery. The heart, brain, liver, lungs and kidneys are the vital organs, but there are another 74 that play a role in keeping us healthy.
