What are the Mesenteries organs?
The mesentery is an organ that attaches the intestines to the posterior abdominal wall in humans and is formed by the double fold of peritoneum. It helps in storing fat and allowing blood vessels, lymphatics, and nerves to supply the intestines, among other functions.

The mesentery attaches the intestines to the abdominal wall, and also helps storing the fat and allows the blood and lymph vessels, as well as the nerves, to supply the intestines.
What are Mesenteries composed of?
The mesentery is composed of two thin layers of fibrofatty tissue, which surrounds and contains the vascular and lymphatic structures supplying either the small bowel or colon. The purpose of the peritoneum and mesentery is to provide a smooth and frictionless surface between the solid organs.
What tissue is Mesenteries?
mesentery, a continuous folded band of membranous tissue (peritoneum) that is attached to the wall of the abdomen and encloses the viscera. In humans, the mesentery wraps around the pancreas and the small intestine and extends down around the colon and the upper portion of the rectum.
What is the difference between peritoneum and mesentery?
The peritoneum is the largest serous membrane of the human body, with a complex structure consisting of ligaments, the greater and lesser omentum, as well as the mesenteries. A mesentery is a double layer of peritoneum, and attaches the vasculature and nerves to the intraperitoneal organs.

It is made of a folded-over ribbon of peritoneum, a type of tissue usually found lining the abdominal cavity. “Without it you can’t live,” says J. Calvin Coffey, a Limerick University Hospital researcher and colorectal surgeon. “There are no reported instances of a Homo sapien living without a mesentery.”
What is a mesenteric tumor?
Abstract. Mesenteric tumors are rare and consist of a heterogeneous group of lesions. Masses may arise from any of the mesenteric components: peritoneum, lymphatic tissue, fat, and connective tissue. Cellular proliferation can also arise from infectious or inflammatory processes.
