Mesentery
Mesenterium · Okruží
Fascia & connective tissue
Looks like
A pleated fan of peritoneum and fat tethering the small intestine to the back wall of the belly.
What it does
Holds the bowel loosely in place and carries its arteries, veins, lymph vessels and nerves.
Keeping it well
A clot or blockage in its arteries starves the bowel: sudden severe belly pain out of proportion to what a doctor can feel, especially with atrial fibrillation, is an emergency.
