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

The gallbladder can be affected by gallstones, which are made up of material that cannot be dissolved, 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, inflammation of the gallbladder, has a wide range of causes, including the result of gallstone impaction, infection, and autoimmune disease.

What Is The Function Of Gallbladder In Our Body

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

Accessory Organs In Digestion: The Liver, Pancreas, And Gallbladder

In adults, the gallbladder measures approximately 7 to 10 cm in length and 4 cm in diameter when fully distended.

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

The gallbladder fossa, against which the fundus and body of the gallbladder lie, lies below the junction of hepatic segments IVB and V.

The cystic duct joins with the common hepatic duct to become the common bile duct. At the junction of the gallbladder neck and the cystic duct, there is an outer pouch of the gallbladder wall forming a mucosal fold known as “Hartmann’s pouch.”

Lymphatic drainage from the gallbladder follows the cystic node, which lies between the cystic duct and the common hepatic duct. Lymphatics from the lower part of the organ drain into the lower liver nodes. All lymph eventually drains into the celiac nodes.

The wall of the gallbladder is made up of several layers. The innermost surface of the gallbladder wall is lined by a single layer of columnar cells with a brush border of microvilli, closely resembling intestinal absorptive cells.

Beneath the epithelium is an underlying lamina propria, a muscular layer, an outer perimuscular layer, and a serosa. Unlike elsewhere in the intestinal tract, the gallbladder does not have a muscularis mucosae and the muscle fibers are not arranged in distinct layers.

The mucosa, the inner portion of the gallbladder wall, consists of a single-layered lining of columnar cells, with cells possessing tiny hair-like insertions called microvilli.

What Is The Gallbladder?

A layer of muscle lies beneath the mucosa. This is made up of smooth muscle, with fibers that are longitudinal, oblique and transverse, and are not arranged in separate layers. The muscle fibers here contract to expel bile from the gallbladder.

A distinctive feature of the gallbladder is the presence of Rokitansky-Aschoff sinuses, deep mucosal exhalations that may extend through the muscle layer and indicate adomiomatosis.

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

Rarely, two or three gallbladders may coexist, either as separate bladders draining into the cystic duct or sharing a common branch draining into the cystic duct. Also, the gallbladder may not form at all. There may also be gall bladders with two lobes separated by a septum. These abnormalities are unlikely to affect function and are generally asymptomatic.

Human Liver Anatomy And Function

The location of the gallbladder in relation to the liver can also vary, with documented variants including gallbladders located within,

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

An anatomical variation can occur, known as the Phrygian cap, which is an innocuous fold of the fundus, named for its resemblance to the Phrygian cap.

Early in development, the human embryo has three germ layers and comes close with an embryonic yolk sac. During the second week of embryogenesis, as the embryo grows, it begins to surround and develop portions of this sac. The developed portions form the basis of the adult gastrointestinal tract. Sections of this foregut begin to differentiate into the organs of the gastrointestinal tract, such as the esophagus, stomach, and intestines.

The Gall Bladder: The Official Of Decision Making And Judgment

During the fourth week of embryological development, the stomach rotates. The stomach, originally located in the midline of the embryo, rotates so that its body is on the left. This rotation also affects the part of the gastrointestinal tube immediately below the stomach, which will become the duodenum. By the fourth week, the developing duodenum begins to sprout a small pouch on its right side, the hepatic diverticulum, which will become the biliary tree. Just below that is a second pouch, known as the cystic diverticulum, which will eventually become the gallbladder.

The main functions of the gallbladder are to store and contract the bile, also called biliary, needed for the digestion of fats in food. Produced by the liver, bile flows through small vessels into the larger hepatic ducts and finally through the cystic duct (parts of the biliary tree) into the gallbladder, where it is stored. At any given time, 30 to 60 milliliters of bile are stored in the gallbladder.

When fatty foods affect the digestive tract, it stimulates the secretion of cholecystokinin (CCK) from I cells in the duodenum and jejunum. In response to cholecystokinin, the gallbladder contracts rhythmically and releases its contents into the common bile duct, eventually draining into the duodenum. Bile emulsifies fats from partially digested food, thus aiding their absorption. Bile consists mainly of water and bile salts, and also acts as a means of removing bilirubin, a product of hemoglobin metabolism, from the body.

What Is Gallbladder Cancer?

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

By removing some water and electrolytes. This is through the active transport of sodium and chloride ions

Across the gallbladder epithelium, which creates an osmotic pressure that also causes water and other electrolytes to be reabsorbed.

One function of the gallbladder appears to be protection against carcinogenesis, as indicated by observations that removal of the gallbladder (cholecystectomy) increases the risk of subsequent cancer. For example, a systematic review and meta-analysis of eight studies concluded that cholecystectomy has a deleterious effect on the risk of right colon cancer.

Another straight study reported a significant increase in total cancer risk, including an increased risk of several different types of cancer, after cholecystectomy.

Most gallstones do not cause symptoms, as the stones remain in the gallbladder or pass through the biliary system.

If the stone blocks the gallbladder, inflammation known as cholecystitis can occur. If the stone lodges in the biliary system, jaundice may appear; if the stone blocks the pancreatic duct, pancreatitis can occur.

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

Case Based Mcq

Known as cholecystitis, inflammation of the gallbladder is usually caused by blockage of the duct with gallstones, which is known as cholelithiasis. Blocked bile builds up and pressure on the gallbladder wall can cause the release of substances that cause inflammation, such as phospholipase. There is also the risk of bacterial infection. An inflamed gallbladder is likely to cause sharp, localized pain, fever, and distention 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. Also, the gallbladder may need to be surgically removed if the inflammation has progressed too far.

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

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

Biliary injury (bile duct injury) is traumatic damage to the bile ducts. It is most commonly an iatrogenic complication of cholecystectomy—surgical removal of the gallbladder—but can also be caused by other operations or major trauma. the risk
