Scientists have discovered what they are calling a new human organ that exists in the digestive system.
Named as mesentery, the organ was previously thought to consist of fragmented and disparate structures.
However, researchers found that it is one continuous organ and outlined evidence to classify it.
The discovery, made by researcher J. Calvin Coffey, has been published in The Lancet Gastroenterology & Hepatology.
Researchers hope that the reclassification will aid better understanding and treatment of abdominal and digestive diseases.
