The mesenteric lymph nodes lie between the layers of the mesentery.
They number from one hundred to one hundred and fifty, and are sited as three groups:
- one group lying close to the wall of the small intestine, among the terminal twigs of the superior mesenteric artery;
- a second group placed in relation to the loops and primary branches of the vessels;
- and a third group located along the trunk of the artery.
