Digestive System Organs: Relationships
A. Relationship
of Digestive Organs to the Peritoneum
1. The visceral peritoneum covers the external
surfaces of most of the digestive organs, and the parietal peritoneum lines the body wall of the abdominopelvic
cavity.
2. The
peritoneal cavity is located between the visceral and parietal peritoneum and
is filled with serous fluid.
3. Mesentery is a double layer of
peritoneum that extends to the digestive organs from the body wall. It allows
blood vessels, lymphatics, and nerves to reach the digestive organs, and holds
the organs in place as well as stores fat.
4. Retroperitoneal organs are found
posterior to the mesentery, lying against the dorsal abdominal wall [most of pancreas
and parts of the large intestine].
