What holds your colon in place?

mesentery
The mesentery is a continuous set of tissues located in your abdomen. It attaches your intestines to the wall of your abdomen and holds them in place. In the past, the researchers thought the mesentery was made up of several separate structures.

What is a peritoneal sac?

The space within the abdomen that contains the intestines, the stomach, and the liver.

What is the lining that holds your organs?

peritoneum
The peritoneum is the serous membrane that forms the lining of the abdominal cavity or the coelom. It covers most of the intra-abdominal, or coelomic, organs. It is composed of a layer of mesothelial tissue, supported by a thin layer of connective tissue.

What does mesenteric panniculitis look like?

It is visualized usually as a heterogeneous mass with a large fat component and interposed linear bands with soft tissue density in cases of mesenteric panniculitis, or as a homogeneous mass of soft tissue density in cases of retractile mesenteritis.

Where is the jejunum?

the small intestine
The middle part of the small intestine. It is between the duodenum (first part of the small intestine) and the ileum (last part of the small intestine).

What does abdominal cavity mean?

abdominal cavity, largest hollow space of the body. Vertically it is enclosed by the vertebral column and the abdominal and other muscles. The abdominal cavity contains the greater part of the digestive tract, the liver and pancreas, the spleen, the kidneys, and the adrenal glands located above the kidneys.

What are the peritoneal organs?

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.

What is the lining of the abdomen called?

The peritoneum covers all of the organs within the tummy (abdomen), such as the bowel and the liver. It protects the organs and acts as a barrier to infection. It has 2 layers. One layer lines the abdominal wall and is called the parietal layer.

What is echogenic mesentery?

Normal mesentery and omentum are echogenic with a coarse architecture but, unlike parenchymal organs such as the liver and kidney, they do not have a distinguishing echotexture. The mesentery normally appears as a “background” echogenicity because it contains fatty tissue.

Is mesenteric panniculitis serious?

Mesenteric panniculitis is usually benign, meaning the condition itself is not dangerous or cancerous. However, complications can occur. Severe inflammation can cause slowing and blockages in the intestines. This can make other symptoms worse, such as nausea and bloating.

What happens to the contents of the large intestine?

As you can see in the picture, intestinal contents move through the ascending colon, across the transverse colon and down through the descending colon. As material moves through the various parts of the large intestine, water and salt are absorbed by the lining and the material is compacted into the stool.

Where are the intestines located in the human body?

The intestines are located inferior to the stomach in the abdominal body cavity. They are connected to the posterior wall of the abdomen by the mesentery, a thin vascular membrane.

What is the back wall of the large intestine called?

Think of your posterior abdominal wall as the “back wall” of your body cavity. Transverse mesocolon. This broad region of the mesentery connects your transverse colon to your posterior abdominal wall. Your transverse colon is the largest section of your large intestine. Left mesocolon.

How does the mesentery keep the intestines in place?

The mesentery attaches your intestines to the wall of your abdomen. This keeps your intestines in place, preventing it from collapsing down into your pelvic area. If the mesentery doesn’t properly form during fetal development, the intestines can collapse or twist.
