Which Structure Contains Nerves and Blood Vessels That Supply the Intestines and Helps Anchor Them in Place?

• A. Omentum
• B. Mucosa
• C. Mesentery
• D. Peritoneum

Answer: (C)

The structure that both anchors the intestines and carries their nerves and blood vessels is the mesentery. It is a fan-shaped double layer of peritoneum that stretches from the posterior abdominal wall to the small intestine, forming a conduit for the mesenteric arteries and veins and the autonomic nerves that supply the gut. This arrangement lets the intestines stay in place while still allowing movement and providing a vascular supply and nerve input. The omentum hangs from the stomach and covers abdominal organs; it contains vessels and fat but isn’t the main anchor or conduit for the intestinal supply. The mucosa is the inner lining of the gut, not a vascular conduit for the intestines. The peritoneum is the broader serous membrane lining the cavity and covering organs, but the specific holding-and-supplying role for the intestines is fulfilled by the mesentery.
