Peritoneum The peritoneum is the serous membrane that forms the lining of the abdominal cavity or coelom in amniotes and some invertebrates, such as annelids. It covers most of the intra-abdominal organs, and is composed of a layer of mesothelium supported by a thin layer of connective tissue. This peritoneal lining of the cavity supports many of the abdominal organs and serves as a conduit for their blood vessels, lymphatic vessels, and nerves. The abdominal cavity is different from the intraperitoneal sp

Peritoneal Cancer Peritoneal Cancer. Peritoneal surface malignancies are cancers that grow or spread along the peritoneal surfaces, the tissues inside the abdomen that line and protect your lungs, chest, and abdomen. Generally, the cancer originates inside the appendix, colon, or pancreas, and spreads into the rest of the abdomen. Peritoneal Mesothelioma.

Peritoneal cancer Peritoneal cancer is cancer that begins in the peritoneum. Peritoneal cancer develops in a similar way to epithelial cancer, which is the most common type of ovarian cancer. This is because the lining of the abdomen and the ovary are very similar types of tissue.

What is the Peritoneal Cavity? The peritoneal cavity is the fluid-filled gap between the wall of the abdomen and the organs contained within the abdomen. The cavity consists of the visceral and the parietal peritoneum.Both are a smooth membranes which excrete fluid.xcess fluid in the peritoneal cavity may cause a swollen abdomen. Problems associated with fluid buildup in the peritoneal cavity may include bruising and swelling of the legs. The peritoneum serves as a tract for lymphatic vessels.

Pelvic Cavity Summary Information: Pelvic Cavity. Pelvic Cavity: The pelvic cavity is an enclosed chamber located within the abdominopelvic cavity that contains some of the body's organs and structures. The pelvic cavity is located below or inferior to the abdominal cavity and includes the bladder, uterus, prostate, urethra, fallopian tubes, anus, and ovaries. The pelvic cavity is lined by the peritoneum.

What is Retroperitoneal? Peritoneal is a term referring or relating to a structure in the abdomen known as the peritoneum. Retroperitoneal, therefore, is a term meaning behind, in back of or posterior to the peritoneum, which is a membrane that serves as a lining for the anatomical space in the abdominal cavity.

- The pericardial cavity is the potential space formed between the two layers of serous pericardium around the heart. Normally, it contains a small amount of serous fluid that acts to reduce surface tension and lubricate. Therefore, the cavity facilitates the free movement of the heart.he pericardial cavity is the potential space formed between the two layers of serous pericardium around the heart.

Abdominal cavity The abdominal cavity is lined with a protective membrane termed the peritoneum. The inside wall is covered by the parietal peritoneum. The kidneys are located in the abdominal cavity behind the peritoneum, in the retroperitoneum. The viscera are also covered by visceral peritoneum.Between the visceral and parietal peritoneum is the peritoneal cavity, which is a potential space. It contains serous fluid that allows motion.he inside wall is covered by the parietal peritoneum. The kidneys are located in the abdominal cavity behind the peritoneum, in the retroperitoneum.

Peritoneum The potential space between these two layers is the peritoneal cavity; it is filled with a small amount (about 50 mL) of slippery serous fluid that allows the two layers to slide freely over each other.

What Is Peritoneal Dialysis? Peritoneal dialysis (PD) is a form of dialysis that uses the lining of your abdomen to filter waste from your blood. PD is done at home. It gets its name from the lining of your abdomen, which is called the peritoneum. This lining is a membrane that surrounds the space called the peritoneal cavity. It’s a miracle of the human body that this natural lining can be used to filter your blood.

- Cancer of the peritoneum is usually attended with fluid exudation in the peritoneal cavity. Take up the mixture of cells and saline in the all-glass syringe and inject into the peritoneal cavity of the rabbit. In the second, fatal acute peritonitis may result from the bursting of an abscess into the peritoneal cavity.

Retroperitoneal space The retroperitoneal space (retroperitoneum) is the anatomical space (sometimes a potential space) in the abdominal cavity behind (retro) the peritoneum.It has no specific delineating anatomical structures. Organs are retroperitoneal if they have peritoneum on their anterior side only.Structures that are not suspended by mesentery in the abdominal cavity and that lie between the parietal peritoneum and abdominal wall are classified as retroperitoneal.The retroperitoneum can be further subdivided into the following:rgans are retroperitoneal if they have peritoneum on their anterior side only. Structures that are not suspended by mesentery in the abdominal cavity and that lie between the parietal peritoneum and abdominal wall are classified as retroperitoneal. The retroperitoneum can be further subdivided into the following:

Brindle A brindle chestnut. Brindle horse with dark bay base coat. Brindle coloring in horses is extremely rare and may be either caused by or somehow linked to chimerism, resulting in an animal with two sets of DNA, with the brindle pattern being an expression of two different sets of equine coat color genes in one horse.ome brindle-colored horses are more eye-catching than others. With this rare coat pattern there is a base coat that covers the entire body of the horse. This base coat color can be any color. Recorded examples have been bay, chestnut, palomino, and dun.

- The mesh is then covered using the lining of the abdominal cavity.2. Totally extraperitoneal approach (TEP): this technique avoids operating within the abdominal cavity. Instead, this procedure is performed outside the abdominal cavity, just above the lining of the abdomen.

Peritoneum The peritoneum is one continuous sheet, forming two layers and a potential space between them: the peritoneal cavity. The outer layer, the parietal peritoneum, is attached to the abdominal wall and the pelvic walls.

Abdominal cavity It is located below (inferior to) the thoracic cavity, and above the pelvic cavity. Its dome-shaped roof is the thoracic diaphragm (a thin sheet of muscle under the lungs), and its oblique floor is the pelvic inlet (the superior opening of the pelvis).he inside wall is covered by the parietal peritoneum. The kidneys are located in the abdominal cavity behind the peritoneum, in the retroperitoneum. The viscera are also covered by visceral peritoneum. Between the visceral and parietal peritoneum is the peritoneal cavity, which is a potential space.

RIXIMKA DUMARKA The abdominal cavity (the space bounded by the vertebrae, abdominal muscles, diaphragm, and pelvic floor) should not be confused with the intraperitoneal space (located within the abdominal cavity, but wrapped in peritoneum). The potential space between these two layers is the peritoneal cavity; it is filled with a small amount (about 50 mL) of slippery serous fluid that allows the two layers to slide freely over each other. 2  The term mesentery is often used to refer to a double layer of visceral peritoneum.

Body cavity For the cloud formation, see Cavum (cloud). A body cavity is any fluid-filled space in a multicellular organism other than those of vessels (such as blood vessels and lymph vessels). The human body cavity normally refers to the ventral body cavity, because it is by far the largest.

- The pelvic cavity is the portion of the ventral body cavity inferior to the abdominal cavity. The bones of the pelvis form the walls of the pelvic cavity, and a layer of muscle forms its floor. The pelvic cavity contains the last portion of the large intestine, the urinary bladder, and various reproductive organs.

Pleural cavity In human anatomy, the pleural cavity is the thin fluid-filled space between the two pulmonary pleurae (visceral and parietal) of each lung. A pleura is a serous membrane which folds back onto itself to form a two-layered membranous pleural sac. The outer pleura (parietal pleura) is attached to the chest wall, but is separated from it by the endothoracic fascia.

- This cavity contains the liver, stomach, spleen, small intestine, and most of the large intestine. (The positions of most of these organs are shown in Figure 1-7c.) These organs are partially or completely enclosed by the peritoneal cavity, much as the heart or lungs are enclosed by the pericardial or pleural cavities.
