The mesentery is a fold of membranous tissue that arises from the posterior wall of the peritoneal cavity and attaches to the intestinal tract.Within it are the arteries and veins that supply the intestine.uring mobilization of the small intestinal mesentery from the posterior abdominal wall, this fold is incised, allowing access to the interface between the small intestinal mesentery and the retroperitoneum.
However, mesentery is often used to describe similar tissues surrounding other organs, such as the large intestines and the appendix. The mesentery has two primary functions: providing support and serving as a conduit for other body systems.omposed of two layers of the membrane peritoneum, mesenteric tissue has sack-like folds that support organs and yet allow them freedom of movement. This arrangement keeps internal organs in place while allowing a body to move around without disturbing the organs.
