What is the primary purpose of the mesentery?

The primary purpose of the mesentery is to provide support to the intestines. It is a fold of tissue in the abdominal cavity that attaches the small and large intestines to the posterior abdominal wall, helping to keep them in place. The mesentery contains blood vessels, nerves, and lymphatics that supply the intestines, allowing for efficient transport of nutrients and removal of waste products. This structural support is crucial for maintaining the proper orientation and function of the intestines during the digestive process.

While the mesentery does play a role in fat storage and has some protective aspects by providing a barrier around abdominal organs, its main function is to serve as a supportive framework for the intestines. It does not primarily function as a filtration mechanism for blood, which is more a role of organs like the kidneys.
