Mesentery

|
In anatomy, the mesentery is a part of the peritoneum that connects an internal organ, such as the small intestine, to the abdominal wall. It does this by long veins branching out directly out of the center of the sack which enclose the organs. The organ receives its blood supply, lymph drainage and nerves through the mesentery.
In invertebrate animals, the term mesentery is also used for any tissue that divides the body cavity (coelom) into partitions.de:Gekröse fr:Mésentčre
