What is the lesser peritoneal cavity?
Anatomical terminology The lesser sac, also known as the omental bursa, is the cavity in the abdomen that is formed by the lesser and greater omentum. Usually found in mammals, it is connected with the greater sac via the omental foramen or Foramen of Winslow.
What does the peritoneal cavity do?
Between its two layers – parietal and visceral – is the peritoneal cavity. The peritoneum functions to support and protect abdominopelvic organs.
What is part of superior level of peritoneal cavity?
The greater sac is the larger portion of the peritoneal cavity. It is further divided into two compartments by the mesentery of the transverse colon (known as the transverse mesocolon): Supracolic compartment – lies above the transverse mesocolon and contains the stomach, liver and spleen.
What is the function of the lesser omentum?
The lesser omentum transports the arteries for the lesser curvature of the stomach; the right and left gastric arteries.
Where is peritoneal cavity found in the body?
The peritoneal cavity is a potential space defined by the diaphragm, walls of the abdominal and pelvic cavities, and abdominal organs. A single layer of parietal peritoneum lines the abdominal wall, the diaphragm, the ventral surface of the retroperitoneal viscera, and the pelvis.
Which is an example of a retroperitoneal organ?
Primarily retroperitoneal organs developed and remain outside of the parietal peritoneum. The oesophagus, rectum and kidneys are all primarily retroperitoneal. Examples of secondarily retroperitoneal organs include the ascending and descending colon.
What organs are included in the peritoneal cavity?
The peritoneum is comprised of 2 layers: the superficial parietal layer and the deep visceral layer. The peritoneal cavity contains the omentum, ligaments, and mesentery. Intraperitoneal organs include the stomach, spleen, liver, first and fourth parts of the duodenum, jejunum, ileum, transverse, and sigmoid colon.
Is the peritoneal cavity part of the parietal layer?
The peritoneal cavity of the abdomen is a potential space between the parietal and the visceral layers of peritoneum. The parietal peritoneum lines the inner surface of the abdominal and pelvic wall.
How does the peritoneum support the abdominopelvic organs?
The peritoneum functions to support and protect abdominopelvic organs. This article will discuss the anatomy of the peritoneum, including key related topics; peritoneal cavity, omenta, mesentery, ligaments, and peritoneal relations.
Where are the greater and lesser sacs in the peritoneal cavity?
The peritoneal cavity can be divided into the greater and lesser peritoneal sacs. The greater sac comprises the majority of the peritoneal cavity. The lesser sac (also known as the omental bursa) is smaller and lies posterior to the stomach and lesser omentum.
Why is the peritoneal cavity called a potential space?
The Peritoneal (Abdominal) Cavity. This fluid acts as a lubricant, enabling free movement of the abdominal viscera, and the antibodies in the fluid fight infection. While the peritoneal cavity is ordinarily filled with only a thin film of fluid, it is referred to as a potential space because excess fluid can accumulate in it,…
