What Body Cavity Is The Gallbladder In – In vertebrates, the gallbladder, also known as the cholecyst, is a small hollow organ where bile is stored and condensed before it is released into the small intestine. In humans, the pear-shaped gallbladder is located under the liver, although the structure and location of the gallbladder can vary significantly between animal species. It receives and stores the bile produced by the liver through the common hepatic duct and releases it through the common bile duct into the duodenum, where the bile helps in the digestion of fats.

The gallbladder can be affected by gallstones, which are formed from material that does not dissolve—usually cholesterol or bilirubin, a breakdown product of hemoglobin. These can cause significant pain, especially in the upper right corner of the abdomen, and are often treated by removing the gallbladder (called a cholecystectomy). Cholecystitis, an inflammation of the gallbladder, has many causes, including the effects of gallstones, infection, and autoimmune disease.

What Body Cavity Is The Gallbladder In

The gallbladder is a hollow gray-blue organ located in a shallow depression below the right lobe of the liver.

Mesentery: Definition, Picture, Anatomy, And Function

In adults, the gallbladder is approximately 7–10 centimeters (2.8–3.9 in) long and 4 centimeters (1.6 in) in diameter when fully expanded.

The gallbladder is divided into three parts: fundus, body and neck. The fundus is the rounded base that is angled so that it faces the abdominal wall. The body is in the depression of the lower surface of the liver. The neck narrows and is continuous with the cystic duct, part of the biliary tree.

The pit of the gallbladder, against which the fundus and body of the gallbladder lie, is found below the junction of segments IVB and V of the liver.

The cystic duct joins with the common hepatic duct to form the common bile duct. At the junction of the gallbladder neck and the cystic duct is an outlet of the gallbladder wall that forms a mucosal fold known as “Hartmann’s pouch.”

Anatomy Of The Peritoneum And Peritoneal Cavity:

The lymphatic drainage of the gallbladder follows the cystic node, which is located between the cystic duct and the common hepatic duct. Lymphatics from the lower part of the organ drain into the lower lymph nodes of the liver. Eventually, all the lymph nodes drain into the celiac.

The gallbladder wall consists of several layers. The innermost surface of the gallbladder wall is lined with a single layer of columnar cells with a brush border of microvilli, which are very similar to intestinal absorptive cells.

Beneath the epithelium is the underlying Lamina propria, the muscular layer, the outer perimuscular layer, and the serosa. Unlike the rest of the intestine, the gallbladder does not have a muscularis mucosa, and the muscle fibers are not arranged in separate layers.

The mucosa, the inner part of the gallbladder wall, is made up of a single layer of columnar cells where the cells have tiny hair-like appendages called microvilli.

Abdomen (human Anatomy)

Beneath the mucosa is a muscular layer. This is formed by smooth muscle, the fibers of which are located in longitudinal, oblique and transverse directions, and are not arranged in separate layers. The muscle fibers here contract and expel the bile from the gallbladder.

A distinctive feature of the gallbladder is the presence of Rokitansky-Aschoff sinuses, deep mucosal outgrowths that may extend through the muscle layer and are suggestive of adomyomatosis.

The outer layer of the base of the gallbladder and the surfaces not in contact with the liver are covered by a thick serosa exposed to the peritoneum.

Rarely, two or three gallbladders may coexist, either as separate gallbladders that drain into the cystic duct, or share a common branch that drains into the cystic duct. In addition, the gallbladder may not form at all. Gallbladders with two lobes separated by a septum may also occur. These abnormalities are unlikely to affect function and are usually asymptomatic.

Anatomy Of The Digestive System

The position of the gallbladder relative to the liver can also vary, and documented variations including the gallbladder are found

Above, on the left side, behind, and detached or suspended from the liver. Such variants are very rare: between 1886 and 1998, only 110 cases of left-sided liver were reported in the scientific literature, or less than one per year.

An anatomic variant known as Phrygian cap can be a harmless macular fold, named for its resemblance to a Phrygian cap.

In the early stage of development, the human embryo has three embryonic layers and is limited to the yolk sac of the embryo. In the second week of the embryo, as the embryo grows, it begins to surround and go around parts of this sac. The transported doses form the basis of the adult’s digestive tract. Parts of this foregut begin to differentiate into organs of the gastrointestinal tract, such as the esophagus, stomach, and intestines.

During the fourth week of embryonic development, the stomach rotates. The abdomen, which initially lies in the midline of the embryo, rotates so that its body is to the left. This rotation also affects the part of the gastrointestinal tract below the stomach that becomes the duodenum. By the fourth week d, the developing duodenum begins to pour out a small outlet on the right side, the hepatic diverticulum, which becomes the biliary tree. Just below this is another outlet, known as a cystic diverticula, which eventually develops into a gallbladder.

The main function of the gallbladder is to store and condense bile, also called bile, which is needed to digest fats in food. Bile produced by the liver flows through small blood vessels into the larger hepatic ducts and finally through the cystic duct (parts of the biliary tree) into the gallbladder, where it is stored. The gallbladder stores 30–60 milliliters (1.0–2.0 US fl oz) of bile at a time.

When fat-containing food nourishes the digestive tract, it stimulates the secretion of cholecystokinin (CCK) from the I cells of the duodenum and jejunum. In response to cholecystokinin, the gallbladder contracts rhythmically and releases its grip on the common bile duct, which eventually drains into the duodenum. Bile emulsifies the fats in partially digested foods, which promotes their absorption. Bile consists mainly of water and bile salts, and it also acts as a way to remove bilirubin, a product of hemoglobin metabolism, from the body.

Viscera Definition And Examples

Bile secreted by the liver and stored in the gallbladder is not the same as bile secreted by the gallbladder. During the storage of the gallbladder, the bile thickens 3-10 times

Removing some water and electrolytes. This occurs through the active transport of sodium and chloride ions

Across the gallbladder epithelium, creating an osmotic pressure that also causes reabsorption of water and other electrolytes.

Gallbladder function appears to be protective against cancer, as evidenced by findings that removal of the gallbladder (cholecystectomy) increases subsequent cancer risk. For example, a systematic review and meta-analysis of eighteen studies concluded that cholecystectomy has an adverse effect on the risk of right-sided colon cancer.

Anatomy And Terminology

Another direct study reported a significantly increased risk of cancer, including an increased risk of several different types of cancer, after cholecystectomy.

Most gallstones do not cause symptoms, but the stones either remain in the gallbladder or travel along the biliary system.

If a stone blocks the gallbladder, the result can be an inflammation known as cholecystitis. If a stone gets stuck in the biliary system, jaundice may occur; if a stone blocks the pancreatic duct, pancreatitis may occur.

Some medications, such as ursodeoxycholic acid, may be used; lithotripsy, a non-invasive mechanical procedure used to break up stones, may also be used.

Inflammation of the gallbladder, known as cholecystitis, is commonly caused by blockage of the duct by gallstones, known as cholelithiasis. Blocked bile builds up, and pressure on the gallbladder wall can lead to the release of inflammatory substances such as phospholipase. There is also a risk of bacterial infection. An inflamed gallbladder is likely to cause sharp and localized pain, fever, and swelling in the upper right corner of the abdomen and may have a positive Murphy’s sign. Cholecystitis is often treated with rest and antibiotics, especially cephalosporins and, in severe cases, metronidazole. In addition, the gallbladder may have to be surgically removed if the inflammation has progressed far.

A cholecystectomy is a procedure in which the gallbladder is removed. It can be removed for recurrent gallstones and is considered an elective procedure. Cholecystectomy can be an operative procedure or laparoscopic. In surgery, the gallbladder is removed from the neck to the fundus,

And thus the bile drains directly from the liver into the biliary tree. About 30 percent of patients may experience some degree of indigestion after the procedure, although serious complications are much rarer.

Biliary tract injury (biliary tract injury) is a traumatic injury to the bile ducts. It is most commonly an iatrogenic complication of cholecystectomy – the surgical removal of the gallbladder, but it can also result from other surgeries or major trauma. Risk
