What is the location and function of the peritoneum?

What is the location and function of the peritoneum?

So let’s start with the basics; the Peritoneum is a serous membrane which lines the walls of the abdominal cavity and lies on abdominal and pelvic organs. Between its two layers – parietal and visceral – is the peritoneal cavity. The peritoneum functions to support and protect abdominopelvic organs.

Where is the peritoneum located in the human body?

abdominal cavity
The peritoneum is the serous membrane that lines the abdominal cavity. It is composed of mesothelial cells that are supported by a thin layer of fibrous tissue and is embryologically derived from the mesoderm.

Where is the precise location of peritoneum?

The outer layer, called the parietal peritoneum, is attached to the abdominal wall. The inner layer, the visceral peritoneum, is wrapped around the internal organs that are located inside the intraperitoneal cavity. The potential space between these two layers is the peritoneal cavity.

What is the peritoneal cavity and where is it located?

The space within the abdomen that contains the intestines, the stomach, and the liver. It is bound by thin membranes.

What is the peritoneal sac?

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.

Is the bladder in the peritoneum?

The bladder is a relatively free organ in the subcutaneous fat of the sub peritoneum except for some fixed ligamentous connections at the bladder neck. The superior and part of the posterior surfaces of the bladder are covered by peritoneum.

What is meant by peritoneal?

Listen to pronunciation. (PAYR-ih-toh-NEE-ul) Having to do with the parietal peritoneum (the tissue that lines the abdominal wall and pelvic cavity) and visceral peritoneum (the tissue that covers most of the organs in the abdomen, including the intestines).

What is the pelvic peritoneum?

The pelvic peritoneal space is the inferior reflection of the peritoneum over the fundus of the urinary bladder and the front of the rectum at the junction of its middle and lower thirds.

What causes peritonitis?

Peritonitis is caused by an infection. Bacteria can enter the lining of your belly from a hole in your GI (gastrointestinal) tract. This can happen if you have a hole in your colon or a burst appendix.

Are the ovaries in the peritoneum?

About the peritoneum The peritoneum is a tissue that lines the abdomen and most of the organs in the abdomen. The tissue covers the uterus, bladder, rectum, and the ovaries and fallopian tubes.

Where is Peritoneal Cancer located?

Peritoneal cancer is a rare type of cancer that develops in the peritoneum. The peritoneum is located in the abdomen. It is a fine sheath that covers the inside wall of the abdomen.

How thick is the peritoneum?

The total area of the peritoneum in an adult human is approximately 1.6-2.04 sq m (16,000-20,400 sq cm), and its thickness is 0.7-1.1 mm. The outer layer of the peritoneum is formed of mesothelium , and its base is composed of fibrous connective tissue. The peritoneum that covers internal organs (visceral peritoneum)…

What is the parietal peritoneum?

Parietal Peritoneum. The parietal peritoneum lines the internal surface of the abdominopelvic wall. It is derived from somatic mesoderm in the embryo. It receives the same somatic nerve supply as the region of the abdominal wall that it lines; therefore, pain from the parietal peritoneum is well localised.

Is the peritoneum an organ?

The peritoneum is not an organ per se, but a lining of the abdominal cavity and almost all abdominal organs. It has a serous surface, minimicing friction between organs, and it helps keep organs in place, which is important to ensure that bloodvessels aren’t streched beyond their limits and also to keep the small and large bowel from making knots.
