But it was sketched by Leonardo Da' Vinci thousands of years ago. According to scientists, they've now discovered yet another human organ that hadn't always been classified as an organ. The mesentery was previously classified as a collection of fragments that connected the intestine to the abdomen.
But now, scientists say that they've found sufficient e nough evidence to formally and scientifically classify the mesentery as an actual organ that is vital to the human body. Researchers aren't quite yet sure what the mesentery does in its whole, but, they reportedly believe that it will help determine future cures for abdominal issues and problems.
