View Full Version : The mesentery: A 'new' organ you didn't know you had

In case you've ever wondered what connects your intestine to your abdomen, there's a word -- and now, a single organ -- for that: the mesentery. But don't worry; you haven't grown a new organ. It's always been there, performing important functions that affect systems throughout the body, from cardiovascular to immunological.

The research of Dr. J. Calvin Coffey, foundation chair of surgery at the University of Limerick, is reclassifying this part of the digestive system as a contiguous organ. In a new study, Coffey has established the anatomy and structure of the mesentery, using images and compiling research to show that the organ's continuity can be seen only when it's exposed in a certain way.

What does it do?

Linking your gut to the rest of your body is an important task, and the mesentery performs it well.
Among its functions, it carries blood and lymphatic fluid between the intestine and the rest of the body. It also maintains the position of the intestine so that it's connected with the abdominal wall without being in direct contact.
That connection is key.
"Without a mesentery to keep the intestine connected, the intestine would have to attach directly to the body wall," Coffey said. "It is unlikely that it would be able to contract and relax along its entire length if it were directly in contact. It maintains the intestine in a particular conformation, 'hitched up,' so that when you stand up or walk about, it doesn't collapse into the pelvis and not function."

Although researchers know that the mesentery plays an important role in the intestinal, vascular, endocrine, cardiovascular and immunological systems, more research is needed to determine the extent of those roles.

But they do have evidence that the mesentery takes environmental signals from the intestine and orchestrates the body's response, Coffey said. One example is how bacteria are sampled in the lymph glands in the mesentery. In response, the glands then coordinate immune responses.


Pretty amazing to discover a new organ in the human body at this point in time.

One of these days they will find the human soul, the mystical portion of our body that you need to be able go to the afterlife.
It's the reason why only humans can go the afterlife, because we are the only ones to have the soul.
At least, that is what I was told.

I have heard mention of the word mesentery in the past so they must have known about it prior.
