The mesentery – which encloses the intestines and attaches them to the wall of the abdomen – seems not to be a fragmented set of incoherent parts, but actually one continuous whole. That means it can be classified as an organ.

The mesentery is a vital part of human existence. As far as we know today, it does three things:

  1. It secretes serous fluid, which decreases friction and allows peristaltic movements that aide in digestion.
  2. It provides a passageway for lymphatics, nerves, arteries and veins between the body wall and internal organs.
  3. It holds the intestines in place.

Yet the function of the mesentery is still being explored, and the recent discovery that it is one continuous organ as opposed to a number of separate parts opens up the door for more research on the functions, ailments, and cures around this life-critical organ.
