 biology - Peritoneum
The peritoneum consists of two layers: the outer layer, called the parietal peritoneum, is attached to the wall of the abdominal cavity and the inner layer, the visceral peritoneum, is wrapped around the organs that are located inside the cavity.
The peritoneum both supports the abdominal organs and serves as a conduit for their blood and lymph vessels and nerves.
Two notable sections of the peritoneum in humans are the omenta, the greater (gastrocolic) omentum and the lesser (gastrohepatic) omentum.

Like all the serous membranes it has a visceral and a parietal layer, the former of which is closely applied to the heart and consists of endothelial cells with a slight fibrous backing: to it is due the glossy appearance of a freshly removed heart.
When the parietal layer is laid open and the heart removed by cutting through the great vessels, it will be seen that there are two lines of reflection of the serous layer, one common to the aorta and pulmonary artery, the other to all the pulmonary veins and the two venae cavae.
This accounts for the fact that the pancreas and duodenum are only covered by peritoneum on their anterior surfaces in man. The formation of the lesser sac is due to the turning over of the stomach to the right, with the result that a cave, known sometimes as the bursa omentalis, is formed behind it.

 Women's Health Issues - Surgeons Re-Assess C-Section Procedure
Closing the parietal peritoneum -- a multi-layered membrane that lines the abdominal-pelvic walls -- after a woman has had a C-section greatly lowers the likelihood of scarring, say researchers at the Stanford University School of Medicine.
The study of 173 with repeat C-sections found that 53 percent of women whose peritoneum was surgically closed following their first C-section delivery developed abdominal adhesions, compared with 73 percent of women who didn't have the surgery.
The researchers concluded that surgical closure of the peritoneum provided five times as much protection against the formation of abdominal adhesions, compared with leaving the membrane to heal on its own.

The spermatic cord in the male and the round ligament of the uterus in the female lie immediately above the anterior margin of the ring, while the inferior epigastric vessels are close to its upper and lateral angle.
The femoral ring is closed by a somewhat condensed portion of the extraperitoneal fatty tissue, named the septum femorale (crural septum), the abdominal surface of which supports a small lymph gland and is covered by the parietal layer of the peritoneum.
The septum femorale is pierced by numerous lymphatic vessels passing from the deep inguinal to the external iliac lymph glands, and the parietal peritoneum immediately above it presents a slight depression named the femoral fossa.
