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.
The mesenteries are sets of thin, transparent sheets of tissue continuous with the peritoneum that suspend and support the visceral organs.Note here the purplish color of the mesentery attached to the small intestine.This is due to the close proximity of both veins (dyed blue) and arteries (dyed red) that transport blood to and from the small intestine. We have now finished dissecting the digestive system!
