Mesenteric Sinuses

Mesenteric sinuses (sinus mesenterici, pna; synonym mesenteric sinuses) are unpaired lymphatic vessels located between the layers of the peritoneum in the mesentery of the small and large intestines. They collect lymph from the lymphatic vessels of the intestine and direct it to the celiac duct tank.

The mesenteric sinuses look like thin-walled oval or spindle-shaped vessels. They pass along the mesenteric arteries and veins, connecting to each other by anastomoses. The number and location of mesenteric sinuses varies.

The mesenteric sinuses play an important role in the drainage of lymph from the intestines and are part of the lymphatic system of the abdominal cavity. Damage or blockage of these vessels can lead to impaired lymphatic drainage and the development of edema.

Mesenteric sinus or mesenteric sinuses

In Russian, unlike English, there is no established name for the mesenteric sinus. It is used only as a synonym or slang word. However, the Russian “sinus” also has an English synonym - **mesenteric foramina**, which literally means mesenteric (mesenteric) openings. Their English name coincides with the accepted term.
